Abstract
Thermal conductivity of UV-crosslinked pressure sensitive adhesives (PSAs) using SiC microparticle as a main filler and SiC nanoparticle grafted graphene oxide (mSiCnano-GO) as an auxiliary filler have been investigated. The introduction of mSiCnano-GO resulted in a homogeneous distribution of fillers without the sedimentation of SiC microparticle. The thermal conductivity and initial tack of PSAs was significantly increased with substituting 0.5-2.0 wt% of mSiCnano-GO filler for SiC microparticle at a fixed total weight fraction of fillers in PSAs, however, the peel strength of PSAs decreased with increasing the mSiCnano-GO fillers. The PSAs showed the thermal conductivity of 0.68 W/m·K at 40 wt% of hybrid filler content which is a 325% improvement compared to the bare-PSA. It is speculated that the enhancement is due to the auxiliary filler chemically bonded with matrix and the facile formation of heat paths between SiCmicro and mSiCnano-GO.

SiC 마이크로입자를 주필러로 사용하고 그래핀 옥사이드가 그래프트된 SiC 나노필러를 보조필러로 사용한 UV 경화형 감압점착제의 열전도도에 대하여 연구하였다. 개질된 SiC 나노필러와 그래핀 옥사이드를 결합시킨 필러(mSiCnano-GO)를 도입한 결과 필러의 침전이 발생하지 않는 균일한 분산을 얻었다. 전체 필러의 함량을 고정시킨 상태에서 SiC 마이크로입자를 mSiCnano-GO로 0.5-2.0 wt% 대체하여 감압점착제의 열전도도와 점착력의 현저한 증가를 관찰하였으나, mSiCnano-GO의 함량이 증가함에 따라 감압점착제의 박리강도는 감소하였다. 40 wt%의 하이브리드 필러를 포함하는 감압점착제의 열전도도는 0.68 W/m·K로 순수 점착제에 비하여 325% 증가하였다. 이와 같은 증가는 보조필러와 기재와의 화학결합과 SiC 마이크로필러와 mSiC-GO 사이에 형성된 열전달 경로 때문으로 여겨진다.
