Hereinafter, with reference to the drawings will be described in detail a temperature-sensitive three-dimensional copolymer with a photocatalyst according to an embodiment of the present invention and a method of manufacturing the same.

먼저, 본 발명의 일 실시예에 따른 광촉매를 구비한 온도감응형 삼차원 공중합체를 설명하기로 한다. First, a temperature-sensitive three-dimensional copolymer having a photocatalyst according to an embodiment of the present invention will be described.

본 발명의 일 실시예에 따른 광촉매를 구비한 온도감응형 삼차원 공중합체는 도 1에 도시한 바와 같이 코어(core) 영역과 쉘(shell) 영역으로 구성된다. 상기 코어 영역은 광촉매와 소수성 고분자로 이루어지고, 상기 쉘 영역은 양친성 고분자로 이루어진다. 이 때, 상기 코어 영역은 광촉매를 중심으로 소수성 고분자가 광촉매를 둘러쌓은 구조로 이룬다. 또한, 상기 코어 영역의 빈 공간은 포집 영역으로 정의된다. The temperature-sensitive three-dimensional copolymer with a photocatalyst according to an embodiment of the present invention is composed of a core region and a shell region as shown in FIG. 1. The core region consists of a photocatalyst and a hydrophobic polymer, and the shell region consists of an amphiphilic polymer. At this time, the core region has a structure in which a hydrophobic polymer surrounds the photocatalyst with respect to the photocatalyst. In addition, the empty space of the core region is defined as a collecting region.

상기 광촉매는 가시광선 또는 자외선이 조사되는 경우 활성산소(singlet oxygen)를 생성하여, 코어 영역의 포집 영역에 포집되는 유기성 유해물질을 이산화탄소(CO2), 물(H2O)로 분해하는 역할을 한다. The photocatalyst generates active oxygen when visible or ultraviolet rays are irradiated, and decomposes organic harmful substances collected in the capture region of the core region into carbon dioxide (CO 2 ) and water (H 2 O). do.

상기 광촉매는 포르피린 복합체(porphyrin complex), Azo, Xanthene, Thiazine, Anthraquinone, Triphenylmethane, Phthalocyanine, Indigo, Quinoline, Phenanthrene, Thionine, Eosin Y, Methyl Orange, Rgodamine B, Methylene Blue, Fluorescein 중 어느 하나가 사용될 수 있다. 또한, 상기 소수성 고분자는 폴리스티렌(polystyrene) 유도체, 폴리아크릴레이트(polyacrylates) 유도체, 폴리메타아크릴레이트(polymethacrylates) 유도체 중 어느 하나로 구성될 수 있다. The photocatalyst may be any one of porphyrin complex, Azo, Xanthene, Thiazine, Anthraquinone, Triphenylmethane, Phthalocyanine, Indigo, Quinoline, Phenanthrene, Thionine, Eosin Y, Methyl Orange, Rgodamine B, Methylene Blue, Fluorescein . In addition, the hydrophobic polymer may be composed of any one of a polystyrene derivative, a polyacrylate derivative, a polymethacrylate derivative.

한편, 상기 쉘 영역을 구성하는 양친성 고분자는 N-Alkylacrylamide 유도체, Poly(vinyl ether), Poly(vinyl methyl ether) 중 어느 하나 형태의 폴리머로 구성될 수 있으며, 구체적으로 P(NIPAm)(Poly(N-isopropyl acrylamide))일 수 있다. 상기 양친성 고분자라 함은 친수성과 소수성을 모두 띠는 고분자를 일컬으며, 본 발명에 있어서 상기 양친성 고분자는 온도에 따라 친수성 또는 소수성을 갖는다. 즉, 상기 양친성 고분자는 임계용액온도(lower critical solution temperature) 이상에서는 소수성을 띠고, 임계용액온도 이하에서는 친수성을 띤다. On the other hand, the amphiphilic polymer constituting the shell region may be composed of any one type of polymer of N-Alkylacrylamide derivative, Poly (vinyl ether), Poly (vinyl methyl ether), specifically P (NIPAm) (Poly ( N-isopropyl acrylamide)). The amphiphilic polymer refers to a polymer having both hydrophilicity and hydrophobicity. In the present invention, the amphiphilic polymer has hydrophilicity or hydrophobicity depending on temperature. In other words, the amphiphilic polymer has hydrophobicity above a critical solution temperature and hydrophilic below a critical solution temperature.

이와 같은 양친성 고분자의 임계용액온도에 따른 친수성, 소수성 특성은 유해물질의 포집 및 삼차원 공중합체의 회수에 이용된다. 구체적으로, 임계용액온도 이하의 용액에서 상기 양친성 고분자는 친수성을 띠게 되며 삼차원 공중합체는 코어 영역과 쉘 영역이 각각 소수성, 친수성을 이룬 상태에서 용액 내에서 부유하게 되며, 이와 같은 상태에서 소수성을 갖는 유해물질이 자유에너지를 낮추기 위해 소수성을 갖는 삼차원 공중합체의 코어 영역으로 이동되어 궁극적으로, 코어 영역의 빈 공간인 포집 영역에 포집된다. 유해물질이 포집 영역에 포집된 상태에서 전술한 바와 같은 광촉매에 의한 분해 반응을 진행할 수 있다. 또한, 임계용액온도 이상의 용액에서 상기 양친성 고분자는 소수성을 띠게 되며 이에 따라, 삼차원 공중합체는 용액 내에서 침전되고 침전된 삼차원 공중합체는 간단한 여과 등을 통해 회수할 수 있다. 참고로, 상기 임계용액온도는 양친성 고분자를 구성하는 물질에 따라 가변적이며, 본 발명에 있어서 임계용액온도는 폐수의 온도보다 높아야 하며 이를 만족하는 물질로 상기 양친성 고분자가 구성되어야 한다. 양친성 고분자가 P(NIPAm)로 구성되는 경우 임계용액온도는 32℃이다. Such hydrophilic and hydrophobic properties according to the critical solution temperature of the amphiphilic polymer is used for the collection of harmful substances and recovery of the three-dimensional copolymer. Specifically, the amphiphilic polymer is hydrophilic in a solution below the critical solution temperature, and the three-dimensional copolymer is suspended in the solution in a state where the core region and the shell region are hydrophobic and hydrophilic, respectively. In order to lower the free energy, the harmful substances are transferred to the core region of the hydrophobic three-dimensional copolymer and are ultimately collected in the empty region of the core region. The decomposition reaction by the photocatalyst as described above may be performed in the state in which the hazardous substances are collected in the collection region. In addition, the amphiphilic polymer becomes hydrophobic in a solution above the critical solution temperature, and thus, the three-dimensional copolymer is precipitated in the solution and the precipitated three-dimensional copolymer can be recovered through simple filtration. For reference, the critical solution temperature is variable according to the material constituting the amphiphilic polymer, in the present invention, the critical solution temperature should be higher than the temperature of the waste water and the amphiphilic polymer should be composed of a material satisfying this. If the amphiphilic polymer consists of P (NIPAm), the critical solution temperature is 32 ° C.

이상, 본 발명의 일 실시예에 따른 광촉매를 구비한 온도감응형 삼차원 공중합체에 대해 설명하였다. 다음으로, 본 발명의 일 실시예에 따른 광촉매를 구비한 온도감응형 삼차원 공중합체의 제조방법을 설명하기로 한다. 본 발명의 일 실시예에 따른 광촉매를 구비한 온도감응형 삼차원 공중합체의 제조방법은 크게 코어 영역 형성단계 및 쉘 영역 형성단계의 순서로 진행된다. 도 2는 본 발명의 일 실시예에 따른 광촉매를 구비한 온도감응형 삼차원 공중합체의 제조방법을 나타낸 모식도이다. In the above, the temperature-sensitive three-dimensional copolymer with a photocatalyst according to an embodiment of the present invention has been described. Next, a method of manufacturing a temperature-sensitive three-dimensional copolymer having a photocatalyst according to an embodiment of the present invention will be described. Method for producing a temperature-sensitive three-dimensional copolymer with a photocatalyst according to an embodiment of the present invention proceeds in the order of the core region forming step and the shell region forming step. Figure 2 is a schematic diagram showing a method for producing a temperature-sensitive three-dimensional copolymer with a photocatalyst according to an embodiment of the present invention.

먼저, 코어 영역 형성단계는 광촉매와 단분자를 분자량조절제(chain transfer agent)를 반응시켜 광촉매의 둘레를 따라 소수성 고분자를 형성하는 단계이다. 상기 광촉매로는 포르피린 복합체(porphyrin complex), Azo, Xanthene, Thiazine, Anthraquinone, Triphenylmethane, Phthalocyanine, Indigo, Quinoline, Phenanthrene, Thionine, Eosin Y, Methyl Orange, Rgodamine B, Methylene Blue, Fluorescein 중 어느 하나가 사용될 수 있으며, 상기 소수성 고분자로는 폴리스티렌(polystyrene) 유도체, 폴리아크릴레이트(polyacrylates) 유도체, 폴리메타아크릴레이트(polymethacrylates) 유도체 중 어느 하나가 이용될 수 있다. 또한, 상기 분자량조절제로는 CTT(carboxyl terminated trithiocarbonates)가 이용될 수 있다. 단분자로 스티렌을 이용하는 경우 상기 코어 영역을 구성하는 소수성 고분자로 폴리스티렌(polystyrene)을 형성할 수 있다. 이 때, 상기 분자량조절제를 통해 코어 영역의 분자량을 조절할 수 있으며, 이를 통해 코어 영역 내 포집 영역의 크기를 조절할 수 있다. 참고로, 분자량조절제의 투입량과 포집 영역의 크기는 반비례 관계를 갖는다. First, the core region forming step is a step of forming a hydrophobic polymer along the circumference of the photocatalyst by reacting a photocatalyst and a single molecule with a chain transfer agent. The photocatalyst may be any one of porphyrin complex, Azo, Xanthene, Thiazine, Anthraquinone, Triphenylmethane, Phthalocyanine, Indigo, Quinoline, Phenanthrene, Thionine, Eosin Y, Methyl Orange, Rgodamine B, Methylene Blue, Fluorescein The hydrophobic polymer may be any one of a polystyrene derivative, a polyacrylate derivative, and a polymethacrylate derivative. In addition, carboxyl terminated trithiocarbonates (CTT) may be used as the molecular weight modifier. When styrene is used as a single molecule, polystyrene may be formed of a hydrophobic polymer constituting the core region. At this time, the molecular weight of the core region can be controlled through the molecular weight regulator, and through this, the size of the trapping region in the core region can be controlled. For reference, the dose of the molecular weight regulator and the size of the trapping region have an inverse relationship.

광촉매와 소수성 고분자로 구성된 코어 영역이 형성된 상태에서, 쉘 영역 형성단계를 진행한다. 구체적으로, 상기 코어 영역을 이루는 복합체 즉, 광촉매와 소수성 고분자의 복합체에 NIPAm(N-isopropyl acrylamide)을 혼합한 다음, RAFT(reversible addition-fragmentation chain-transfer) 반응을 통해 P(NIPAm)(poly-NIPAm)로 이루어지는 쉘 영역의 고분자를 형성한다. 이 때, 상기 NIPAm의 혼합량을 통해 P(NIPAm)의 분자량을 조절할 수 있으며, P(NIPAm)의 분자량이 커질수록 친수성시 용해도가 커진다. In the state where the core region composed of the photocatalyst and the hydrophobic polymer is formed, the shell region forming step is performed. Specifically, N-isopropyl acrylamide (NIPAm) is mixed in a complex constituting the core region, that is, a photocatalyst and a hydrophobic polymer complex, and then P (NIPAm) (poly-) through a reversible addition-fragmentation chain-transfer (RAFT) reaction. The polymer of the shell region which consists of NIPAm) is formed. At this time, the molecular weight of P (NIPAm) can be adjusted through the mixed amount of the NIPAm, the higher the molecular weight of P (NIPAm), the greater the solubility in hydrophilicity.
