본 발명은 양쪽성 즉, 계면활성능을 가지는 우레탄 아크릴레이트 전구체를 이용하여서 여러 가지 폴리올에 은 나노입자를 형성, 분산시키고 이를 이용하여서 디이소시아네이트와 반응시켜서 은 나노 입자가 안정하게 분산된 폴리우레탄 나노복합체를 제조하는 것이다.According to the present invention, polyurethane nanoparticles in which silver nanoparticles are stably dispersed by forming and dispersing silver nanoparticles in various polyols by using an amphoteric, urethane acrylate precursor having surfactant activity and reacting with diisocyanate using the same. To prepare a complex.

일반적으로 은 나노입자를 고분자에 분산시키기 위해서는 은 나노입자가 분산된 유기용액을 고분자에 혼합하여서 제조하거나, Vapor Deposition을 통하여서 Silver Salt를 고분자 필름 위에 도포하거나, Silver Salt를 고분자와 혼합하고, 이후, 고온에서 처리하여서 은 나노입자를 형성시키는 것이 일반적이다. 그러나, 무용매 공정을 통하여서 합성되는 고분자 재료의 경우, 은 나노입자를 분산시키는 것은 매우 어려운 일이다. 즉, 무용매 공정으로 One-shot으로 합성되는 폴리우레탄폼이나 폴리우레탄 탄성체 공정에 기존 은 나노입자 합성공정을 적용은 현실적으로 불가능하다. 일반적인 폴리우레탄 폼이나 탄성체 합성공정은 무용매하에서 One-Shot 공정을 통하여서 합성되므로, 기존의 은 나노입자 합성 공정을 적용하는 것은불가능한 일이다. 따라서, 은 나노입자가 분산된 폴리우레탄 폼이나 탄성체를 합성하기 위해서는 기존의 폴리우레탄 픔, 탄성체 합성공정에 적합한 공정을 개발하는 것이 필수적이다. 따라서, 본 발명에서는 기존의 폴리우레탄 합성 공정에 직접 적용이 가능한 폴리우레탄/은 나노복합체 합성공정에 관한 것이다.In general, in order to disperse silver nanoparticles in a polymer, an organic solution in which silver nanoparticles are dispersed is prepared by mixing with a polymer, silver salt is applied onto a polymer film through vapor deposition, or silver salt is mixed with a polymer. It is common to form silver nanoparticles by treatment at high temperature. However, in the case of the polymer material synthesized through the solventless process, it is very difficult to disperse the silver nanoparticles. That is, it is practically impossible to apply the existing silver nanoparticle synthesis process to the polyurethane foam or polyurethane elastomer process synthesized as a one-shot in a solvent-free process. Since a general polyurethane foam or elastomer synthesis process is synthesized through a one-shot process under a solvent, it is impossible to apply a conventional silver nanoparticle synthesis process. Therefore, in order to synthesize a polyurethane foam or an elastomer in which silver nanoparticles are dispersed, it is essential to develop a process suitable for the existing polyurethane foam and elastomer synthesis process. Therefore, the present invention relates to a polyurethane / silver nanocomposite synthesis process that can be applied directly to the existing polyurethane synthesis process.

본 발명은 상기의 기존의 고분자/은 나노복합체 제조상의 문제점을 해결하기 위한 기술로, 리빙중합, 개환중합법에 비해서 매우 간단하고 단순한 실험 조건하에서 양쪽성을 가지는 비이온성 우레탄 아크릴레이트 전구체를 합성하고 이를 이용하여서 은 나노입자를 폴리올에 나노 크기로 분산시킨다. 이렇게 은 나노입자가 분산된 폴리올을 여러 가지 디이소시아네이트와 반응시켜서 은 나노입자가 분산된 폴리우레탄을 제조한다. 즉, 은 나노입자가 분산된 폴리올을 우선적으로 합성하고, 이를 기존의 폴리우레탄 제조 공정에 직접 이용하여서 은 나노입자가 분산된 폴리우레탄을 제조하는 것이다.The present invention is a technique for solving the problems of the conventional polymer / silver nanocomposite, synthesized a nonionic urethane acrylate precursor having amphoteric under very simple and simple experimental conditions compared to living polymerization, ring-opening polymerization method By using this, silver nanoparticles are dispersed in polyol in nano size. The polyol in which silver nanoparticles are dispersed is reacted with various diisocyanates to prepare polyurethane in which silver nanoparticles are dispersed. That is, the polyol in which silver nanoparticles are dispersed is preferentially synthesized, and this is directly used in an existing polyurethane manufacturing process to prepare polyurethane in which silver nanoparticles are dispersed.

본 발명에서 사용되는 비이온성 양쪽성 우레탄 아크릴레이트는 계면활성능을 가지고 있는 물질이기 때문에, 형성되는 나노 금속입자와 일종의 Complex를 형성하여서 나노 입자들이 안정하게 분산될 수 있는 역할을 한다. 즉, 양쪽성 우레탄 아크릴레이트를 폴리올에 혼합, 용해시킨 후, Silver Salt를 첨가, 혼합하여서 Silver Salt를 용해시킨다. 이후, 온도를 상승시켜서 라디칼에 의한 전자 이동 반응을 통하여서 은 나노 입자를 형성시켜 폴리올에 분산시킨다. 이 때, 양쪽성 우레탄 아크릴레이트는 Silver Salt를 용해시키는 작용을 할뿐만 아니라, 형성되는 은나노입자가 서로 응집되지 못하게 하는 작용을 한다. 이렇게 제조된 폴리올을 일정 몰비로 디이소시아네이트와 반응하여서 최종적으로 은 나노 입자가 분산된 폴리우레탄을 합성한다. 이러한 공정을 이용하여서 폴리우레탄/은 나노복합체를 합성하는 경우, 기존의 공정과는 달리 용매를 사용하지 않고도 은 나노 입자를 용이하게 고분자내에 분산시킬 수 있을 뿐만 아니라, 기존의 폴리우레탄 제조 공정에도 직접 적용이 가능하다.Since the nonionic amphoteric urethane acrylate used in the present invention is a material having an interfacial activity, it forms a kind of complex with the nanometal particles to be formed and serves to stably disperse the nanoparticles. That is, the amphoteric urethane acrylate is mixed and dissolved in a polyol, and then silver salt is added and mixed to dissolve the silver salt. Thereafter, the temperature is increased to form silver nanoparticles through the electron transfer reaction by radicals, which are then dispersed in the polyol. At this time, the amphoteric urethane acrylate not only functions to dissolve the silver salt, but also to prevent the silver nanoparticles formed from aggregation with each other. The polyol thus prepared is reacted with diisocyanate at a constant molar ratio to finally synthesize a polyurethane in which silver nanoparticles are dispersed. When synthesizing polyurethane / silver nanocomposites using this process, silver nanoparticles can be easily dispersed in a polymer without using a solvent, unlike conventional processes, and can be directly applied to a conventional polyurethane manufacturing process. Application is possible.
