Abstract

In this study, we prepared a silver nanoparticle transferable adhesive composition with transparency and adhesive properties using UV-curable urethane acrylate containing silane groups. The urethane-based adhesive composition was applied between the Ag/PET film in which silver nanoparticles were patterned on PET and the PC film to be transferred. Immediately after UV-curing with UV, PET was removed to complete the manufacture of Ag/PC film. UV-curable urethane acrylate containing silane groups was synthesized using polycaprolactone diol (PCL), isophrone diisocyanate (IPDI), 2-hydroxyethyl methacrylate (HEMA), and (3-aminopropyl) triethoxysilane (APTES). The silane group of APTES can improve interfacial adhesion by reacting with the specially treated silver nanoparticle surface of the Ag/PET film. In addition, we improved the adhesion between silver nanoparticle and PC film by mixing UV-curable urethane acrylate containing a silane group and a functional acrylic diluent used as a diluent. We analyzed the synthesis process of urethane acrylate using FT-IR, and compared the adhesive properties, optical properties, and transfer properties according to the molar ratio of APTES and the acrylic diluent composition. As a result, the best transfer properties were confirmed in the adhesive composition prepared under the conditions of PUA2S1_0.5.

본 연구에서는 실란기가 도입된 UV 경화형 우레탄 아크릴레이트를 사용하여 투명성 및 접착성/이형성을 갖춘 silver nanoparticle 전사용 접착 조성물을 제조하였다. Silver nanoparticle이 PET 위에 패터닝되어 있는 Ag/PET 필름과 전사 대상인 PC필름 사이에 제조한 접착 조성물을 도포하고 UV로 광경화한 후, PET를 제거하여 Ag/PC 필름을 제조하였다. 실란기가 도입된 UV 경화형 우레탄 아크릴레이트는 polycaprolactone diol (PCL)과 isophrone diisocyanate (IPDI), 2-hydroxyethyl methacrylate (HEMA), (3-aminopropyl)triethoxysilane (APTES)를 사용하여 합성하였다. APTES의 실란기는 특수 처리된 Ag표면과 반응하여 계면접착력이 개선될 수 있으며, 실란기가 도입된 우레탄 아크릴레이트와 희석제로 투입하는 기능성 아크릴 희석제에 의하여 PC필름과의 접착력을 향상시켰다. 우레탄 아크릴레이트 합성은 FT-IR을 이용하여 분석하였으며, APTES의 몰비와 아크릴 희석제 조성에 따라, 접착 특성과 광학 특성, 전사 특성 등을 비교하였다. 결과적으로, PUA2S1_0.5의 조건으로 제조된 접착 조성물에서 가장 우수한 전사 특성을 확인하였다.
