Description
[001] Os polímeros inteligentes, são materiais capazes de responder a um estímulo, apresentando mudanças físicas ou químicas em seu comportamento, tendo aplicações biomédicas, industriais, farmacêuticas, alimentícias, hardware, eletrônica entre outras. A presente invenção descreve uma mistura de polímeros iônicos na forma de uma blenda polimérica do tipo semi-IPN à base de poliacrilatos e polieletrólitos de cadeia linear ou ramificada. Esta blenda demonstrou funções variantes de acordo com o tipo de estímulo (elétrico, mecânico ou térmico). Ao ser aplicada uma tensão elétrica em corrente contínua, a blenda produz movimento, quando disposta entre dois eletrodos flexíveis sobrepostos ao filme. Ao ser aplicada uma pressão mecânica sobre a blenda, é gerada uma diferença de potencial elétrico nas faces do filme polimérico, podendo esta eletricidade ser armazenada, utilizada como sensor de movimento mecânico, sensor de pressão ou amortecedor-gerador, além das funções iniciais de atuador. Também apresenta potencial termoelétrico como sensor de temperatura e gerador termoelétrico.[001] Intelligent polymers are materials capable of responding to a stimulus, presenting physical or chemical changes in their behavior, having biomedical, industrial, pharmaceutical, food, hardware, electronics applications, among others. The present invention describes a mixture of ionic polymers in the form of a polymer blend of the semi-IPN type based on polyacrylates and linear or branched polyelectrolytes. This blend demonstrated variant functions according to the type of stimulus (electrical, mechanical or thermal). When an electric voltage is applied in direct current, the blend produces movement, when disposed between two flexible electrodes superimposed on the film. When mechanical pressure is applied to the blend, a difference in electrical potential is generated on the faces of the polymeric film, and this electricity can be stored, used as a mechanical motion sensor, pressure sensor or shock absorber-generator, in addition to the initial actuator functions . It also has thermoelectric potential as a temperature sensor and thermoelectric generator.

[003] Polieletrólitos são polímeros que apresentam carga quando estão solubilizados ou imersos em um liquido altamente polar como a água. Pode-se citar nesta categoria o poli (ácido acrílico), (6,6-ioneno) N, poli (2-vinil-piridina), poli (lisina), poli (cloreto de dialildimetilamônio), poli (acrilato de dimetilaminoetil), poli (ácido metacrílico), poli (etileno imina) , poli (ácido estireno sulfônico), poli (ácido glutâmico), poli (sulfato de vinila), poli (ácido de acrilamida-co-acrílico), ácido hialurônico, quitosana, carboximetil celulose e DNA (fita simples) (HOAGLAND, David. Polyelectrolytes. Encyclopedia of Polymer Science and Technology, v.7, p.439-504, 2002). Entretanto a utilização combinada destas duas categorias de materiais (poliacrilatos e polieletrólitos), não foram descritas para a obtenção de atuadores, geradores e sensores poliméricos.[003] Polyelectrolytes are polymers that present a charge when they are solubilized or immersed in a highly polar liquid such as water. This category includes poly (acrylic acid), (6,6-ionene) N, poly (2-vinyl-pyridine), poly (lysine), poly (diallyldimethylammonium chloride), poly (dimethylaminoethyl acrylate), poly (methacrylic acid), poly (ethylene imine), poly (styrene sulfonic acid), poly (glutamic acid), poly (vinyl sulfate), poly (acrylamide-co-acrylic acid), hyaluronic acid, chitosan, carboxymethyl cellulose and DNA (single strand) (HOAGLAND, David. Polyelectrolytes. Encyclopedia of Polymer Science and Technology, v.7, p.439-504, 2002). However, the combined use of these two categories of materials (polyacrylates and polyelectrolytes) have not been described for obtaining actuators, generators and polymeric sensors.
[004] Polímeros eletroativos apresentam, entre outras especificidades, mecanismo de movimentação baseado em migração iônica dentro da malha polimérica (RU, Jie et al., Smart Materials and Structures, v. 27, n. 2, p. 02LT01, 2018). Alguns destes materiais ainda possuem a capacidade de produzir uma diferença de potencial elétrico ao ser aquecido em uma de suas faces/extremidades (CULEBRAS, Mario; GÓMEZ, Clara M.; CANTARERO, Andrés. Materials, v. 7, n. 9, p. 6701-6732, 2014.).[004] Electroactive polymers have, among other specificities, a movement mechanism based on ionic migration within the polymeric mesh (UK, Jie et al., Smart Materials and Structures, v. 27, n. 2, p. 02LT01, 2018). Some of these materials still have the ability to produce a difference in electrical potential when heated on one of their faces / ends (CULEBRAS, Mario; GÓMEZ, Clara M .; CANTARERO, Andrés. Materials, v. 7, n. 9, p . 6701-6732, 2014.).
[005] Esta classe de materiais tem sido estudada para utilização na indústria médico-hospitalar, produzindo músculos artificiais (TOLBAH, Farid A. et al, Research and Education in Mechatronics (REM), 2014 15th International Workshop on. IEEE, 2014. p. 1-7.), órteses para ventrículo (HOSSEINIPOUR, M.; ELAHINIA, M., Bioinspiration, Biomimetics, and Bioreplication 2013.

Jong; REINHALL, Per G.; SEIBEL, Eric J., Sensors and Actuators A: Physical, v. 133, n. 2, p. 506-517, 2007.). Entretanto, não foi ainda descrito, nenhum poliacrilato associado a um polieletrólito na forma de blenda polimérica.[005] This class of materials has been studied for use in the medical-hospital industry, producing artificial muscles (TOLBAH, Farid A. et al, Research and Education in Mechatronics (REM), 2014 15th International Workshop on.

However, no polyacrylate associated with a polyelectrolyte in the form of a polymer blend has yet been described.
[006] Estudos na área de sensores e atuadores apontam para a utilização predominante de um polímero perfluorado sulfonado como material que permite a troca de íons, tornando-o o material padrão para tais utilizações (CHATTARAJ, Ritwik et al., Sensors and Actuators A: Physical, v. 270, p. 65-71, 2018). Entretanto, nenhuma menção ao uso de poliacrilato associado a um polieletrólito numa blenda polimérica, foi citada na literatura.[006] Studies in the area of sensors and actuators point to the predominant use of a perfluorinated sulfonated polymer as a material that allows the exchange of ions, making it the standard material for such uses (CHATTARAJ, Ritwik et al., Sensors and Actuators A : Physical, v. 270, p. 65-71, 2018). However, no mention of the use of polyacrylate associated with a polyelectrolyte in a polymer blend has been cited in the literature.
[007] A patente US2015287906 (A1) com o título de POLYMER BLENDS OF ELECTROSTRICTIVE TERPOLYMER WITH OTHER POLYMERS na data 2009-10-15 descreve um atuador que faz uso de uma blenda polimérica à base de fluoreto de polivinilideno somado a um terpolímero derivado do fluoreto de polivinilideno ou polivinilfluoruro. No entanto, esta invenção limita a metodologia de produção a uma blenda multicamadas e não abrange a utilização termoelétrica da blenda de poliacrilato associada a um polieletrólito.[007] The patent US2015287906 (A1) with the title of POLYMER BLENDS OF ELECTROSTRICTIVE TERPOLYMER WITH OTHER POLYMERS on the date 2009-10-15 describes an actuator that makes use of a polymer blend based on polyvinylidene fluoride added to a terpolymer derived from polyvinylidene fluoride or polyvinyl fluoride. However, this invention limits the production methodology to a multilayer blend and does not cover the thermoelectric use of the polyacrylate blend associated with a polyelectrolyte.
[008] A patente US6475639B2 com o título IONIC POLYMER SENSORS AND ACTUATORS descreve o método de produção para um dispositivo com múltiplas aplicações baseado em um compósito que consiste em um filme de polímero perfluorado sulfonado e eletrodos de Lítio depositados quimicamente para ser utilizado como sensor de movimentos ou atuador, não abrangendo a utilização termoelétrica ou de sensor de pressão da blenda de poliacrilato associada a um polieletrólito.[008] US6475639B2 with the title IONIC POLYMER SENSORS AND ACTUATORS describes the production method for a device with multiple applications based on a composite consisting of a sulfonated perfluorinated polymer film and chemically deposited lithium electrodes to be used as a sensor for movements or actuator, not covering the use of a thermoelectric or pressure sensor of the polyacrylate blend associated with a polyelectrolyte.
[009] A exemplo de dispositivos com função de sensor e atuador, foi desenvolvido um compósito de grafeno e polianilina (KHMELNITSKIY, Ivan K. et al., Young Researchers in Electrical and Electronic Engineering. IEEE, 2018. p. 419-422). Como atuador e gerador utilizou-se um polímero perfluorado sulfonado e prata (ZHAO, Yang et al., Polymers (20734360), v. 10, n. 7, 2018). Como gerador termoelétrico utilizou-se um compósito à base de polieterimida e nanotubos de carbono (TZOUNIS, Lazaros et al., Composites Science and Technology, v. 156, p. 158-165, 2018). Como sensor térmico utilizou-se polivinilfluorideno (PARKER, Adrian et al., Journal of Polymer Science & Applications, v. 2018, 2018) ou como sensor de pressão utilizou-se um compósito baseado em poliimida e nanotubos de carbono (NELA, Luca et al., Nano letters, v. 18, n. 3, p. 2054-2059, 2018). Em nenhum destes trabalhos foi utilizada uma blenda polimérica à base de poliacrilato associada a um polieletrólito. O experimento utilizando poliacrilamida associada a cloreto de sódio para formar um hidrogel iônico (KEPLINGER, Christoph et al., Science, v. 341, n. 6149, p. 984-987, 2013), apresentou resposta sob alta tensão elétrica (acima de 3 kV), tornando-o pouco viável para diversos usos práticos, não sendo produzida blenda polimérica ou compósito utilizando um poliacrilato associado a um polieletrólito.[009] Like devices with sensor and actuator function, a graphene and polyaniline composite was developed (KHMELNITSKIY, Ivan K. et al., Young Researchers in Electrical and Electronic Engineering. IEEE, 2018. p. 419-422) . As an actuator and generator, a sulfonated and silver perfluorinated polymer was used (ZHAO, Yang et al., Polymers (20734360), v. 10, n. 7, 2018). As a thermoelectric generator, a composite based on polyetherimide and carbon nanotubes was used (TZOUNIS, Lazaros et al., Composites Science and Technology, v. 156, p. 158-165, 2018). As a thermal sensor, polyvinylfluoridene was used (PARKER, Adrian et al., Journal of Polymer Science & Applications, v. 2018, 2018) or as a pressure sensor, a composite based on polyimide and carbon nanotubes (NELA, Luca et al., Nano letters, v. 18, n. 3, p. 2054-2059, 2018). In none of these works was a polymer blend based on polyacrylate associated with a polyelectrolyte. The experiment using polyacrylamide associated with sodium chloride to form an ionic hydrogel (KEPLINGER, Christoph et al., Science, v. 341, n. 6149, p. 984-987, 2013), showed a response under high electrical voltage (above 3 kV), making it not viable for several practical uses, and no polymer blend or composite is produced using a polyacrylate associated with a polyelectrolyte.
[010] Não há estudos publicados na área onde polímeros inteligentes exerçam simultaneamente com as funções múltiplas de atuador, gerador eletromecânico, gerador termoelétrico, sensor térmico e de pressão. Todos os trabalhos apresentados até o momento não utilizam um único material com a função simultânea de atuador, gerador eletromecânico ou sensor mecânico, tampouco utilizam uma blenda polimérica baseada em poliacrilatos e polieletrólitos.[010] There are no published studies in the area where intelligent polymers exercise simultaneously with the multiple functions of actuator, electromechanical generator, thermoelectric generator, thermal and pressure sensor. All the works presented so far do not use a single material with the simultaneous function of an actuator, electromechanical generator or mechanical sensor, nor do they use a polymer blend based on polyacrylates and polyelectrolytes.
[011] A presente invenção descreve a produção de uma blenda polimérica do tipo semi-IPN (Figura 1) utilizada como atuador, gerador flexogelelétrico, gerador termoelétrico, sensor mecânico e sensor de temperatura. A Figura 1 representa graficamente a organização de uma blenda polimérica do tipo semi-IPN, onde o polímero base é a poliacrilamida (Figura 1-A), ou outro polímero do grupo dos acrilatos do tipo hidrogel que é formado pela ação de um agente reticulante (Figura 1-B), e um segundo polímero, o poli-4-estirenossulfonato de sódio, ou outro polímero de cadeia linear do tipo polieletrólito (Figura 1-C).O filme polimérico apresenta-se na forma de hidrogel, cuja cadeia reticulada (Figura 2) retém o polímero de cadeia linear, juntamente com a água solvatada, dentro de sua malha. Tal arquitetura permite a migração do polieletrólito, da água solvatada, bem como do sal acrescido à solução precursora da blenda, de acordo com o campo elétrico, movimento ou temperatura aplicados ao filme.Para a síntese do polímero reticulado (Figura 2) é realizada uma reação de poliadição do tipo sol-gel onde meros de acrilamida (ou de outro mero hidrofílico da família do acrilato) (Figura 2-A) reagem entre si e com o agente reticulante bis-acrilamida (ou outro agente reticulante) (Figura 2-B) e a consequente produção da poliacrilamida reticulada (Figura 2-C).O polímero de cadeia linear do tipo polieletrólito (no caso o poli-4-estirenossulfonato de sódio) (Figura 3) do sistema semi-IPN é acrescido antes da reação inicial, podendo este possuir propriedades catiônicas (Figura 3-A) ou aniônicas (Figura 3-B).[011] The present invention describes the production of a semi-IPN polymer blend (Figure 1) used as an actuator, flexogelelectric generator, thermoelectric generator, mechanical sensor and temperature sensor. Figure 1 graphically represents the organization of a polymer blend of the semi-IPN type, where the base polymer is polyacrylamide (Figure 1-A), or another polymer in the group of acrylates of the hydrogel type that is formed by the action of a crosslinking agent (Figure 1-B), and a second polymer, sodium poly-4-styrenesulfonate, or another straight-chain polymer of the polyelectrolyte type (Figure 1-C). The polymeric film is in the form of a hydrogel, whose chain cross-linked (Figure 2) retains the linear chain polymer, together with solvated water, within its mesh. Such architecture allows the migration of the polyelectrolyte, the solvated water, as well as the salt added to the precursor solution of the blend, according to the electric field, movement or temperature applied to the film. For the synthesis of the cross-linked polymer (Figure 2), a polyaddition reaction of the sol-gel type where acrylamide (or other hydrophilic mere of the acrylate family) (Figure 2-A) react with each other and with the bis-acrylamide crosslinking agent (or other crosslinking agent) (Figure 2- B) and the consequent production of the cross-linked polyacrylamide (Figure 2-C). The linear polymer of the polyelectrolyte type (in this case the sodium poly-4-styrenesulfonate) (Figure 3) of the semi-IPN system is added before the reaction initial, which may have cationic (Figure 3-A) or anionic (Figure 3-B) properties.
