초록

아크릴 점착제는 고내구성 및 분자량 조절, 관능기의 도입 등이 용이하여 반도체, 디스플레이, 모바일 기기, 자동차 등의 첨단 산업에서 매우 다양하게 활용되고 있다. 점착제의 점착물성은 산업에서의 적용, 공정관리, 제품의 신뢰성에 지대한 영향을 미치기에 그 중요성이 날로 더해가고 있다. 본 연구에서는 조합기법을 이용하여 아크릴 점착제의 물성 영향인자 가운데 두께의 변화에 따른 점착물성 변화를 살펴보고자 한다. 아크릴 점착제는 2-ethylhexyl acrylate와 acrylic acid로 구성된 기본점착제만을 활용하여 샘플을 제작하였으며, 두께 구배가 가능한 micro applicator를 활용하여 thickness-gradient acrylic PSA 샘플을 제작하였으며, 이를 기존의 코팅법으로 제작한 샘플과 비교함으로써 조합기법의 재현성을 평가하였다.

Acrylic pressure sensitive adhesives (PSAs) are used in various field of high-technology industries such as semiconductor, display, mobile, automobile, and so on. Because of they have high durabilities and can be easily introduced functional groups in their molecular structures. PSA perfomances has an effect on their applications in industry process operation, reliability of final products. In this study, PSA performances as a function of fim thickness which is one of the impact factors effects on PSA performances will be investigated using combinatorial methods. Acrylic PSAs are synthesized using 2-ethylhexyl acrylate and acrylic acid. Thickness-gradient of acrylic PSA sample is made by a micro applicator. We compare general coating method with thickness-gradient coating method and evaluate the reappearance of combinatorial methods compared with existing coating method. Thickness-gradient of acrylic PSA sample shows rough and broad data tendency.
