Abstract

The dispersion of graphene nanoplates (GNPs) in polypropylene (PP)/GNP composites and the compatibility of PP and GNP were investigated. (3-aminopropyl)triethoxysilane (APTES) was used for GNP modification, and FTIR spectroscopy was used to confirm the modification of GNPs. To improve the compatibility of PP and GNPs, maleic anhydride (MAH) grafted PP (PP-g-MAH) fabricated by reactive extrusion was used. In the composite where GNP modification and PP-g-MAH were simultaneously applied, the crystallization temperature increased, unlike other composites. This is interpreted as being due to the improved compatibility of GNPs. The contact angle change was examined to confirm the improvement in compatibility.


그래핀나노플레이트(graphene nanoplate, GNP) 개질 및 상용화제가 적용된 폴리프로필렌(polypropylene, PP)/GNP 복합체의 GNP 분산성 그리고 PP와 GNP의 상용성을 고찰하였다. GNP 개질에는 (3-aminopropyl)triethoxysilane (APTES)를 이용하였으며, GNP의 개질 여부 확인을 위해 적외선 분광기(FTIR)을 이용하였다. PP와 GNP의 상용성 개선을 위해 무수말레인산(maleic anhydride, MAH)이 그라프트된 PP(PP-g-MAH)를 반응압출하여 사용하였다. GNP 개질과 PP-g-MAH가 동시에 적용된 복합체의 경우 다른 복합체들과 다르게 결정화온도가 증가하였으며, 이는 GNP의 상용성 개선에 의한 것으로 해석되며, 상용성 개선을 확인하기 위해 접촉각 변화를 고찰하였다.
