초록
최근 미래 모빌리티 시장의 급격한 성장으로 자동차에 전장부품이 다량 탑재되면서 부품간 오작동을 최소화하기 위해 자동차 시장에서도 전자파 차폐에 대한 중요성이 커지고 있다. 이에 따라 전기전도성 고분자 복합소재(Conductive Polymer Composites, CPC)가 자동차용 차폐재로 각광받고 있으나, 산업에 일반적으로 요구되는 20 dB 이상의 전자파 차폐 성능 달성을 위해서는 고 함량의 전도성 필러 충진이 요구되므로 기계적 물성 향상, 원가 절감 측면에서 CPC의 전도성 필러 함량을 줄이기 위한 연구가 필수적이다. 본 논문에서는 이 중 필러 함량을 획기적으로 줄일 수 있는 Segregated structure 필러 네트워크 기반의 CPC를 제조하기 위한 공법들을 소개하고, 각 제조 공법 별 전자파 차폐 성능을 비교하고 분석하였다.
Abstract
With the rapid growth of the future mobility market, a large number of electronic parts are being used in automobile, and the importance of electromagnetic interference (EMI) shielding in the automobile market is growing to minimize malfunctioning among the parts. Accordingly, conductive polymer composites (CPCs) are getting a lot of attention as EMI shielding materials for the automotive, but there are still challenges in CPCs like high content of conductive filler to achieve proper EMI shielding effectiveness, and poor mechanical properties. This paper introduces main methods to manufacture CPCs with segregated filler structure, which can significantly reduce the filler content, and analyzes EMI shielding performance of each manufacturing method.
