ketone. We achieve relatively good dispersion in aprotic and non-polar solvents by controlling the C/O atomic ratio of the PRGOs and applying the two-phase solvent exchange method. There is an increase in the glass transition temperatures with the dispersion of PRGOs into amorphous polymers, in particular a 4.4°C increase for poly(methyl methacrylate) and 3.0°C increase for polycarbonate. Good dispersion of PRGO in a nonpolar polymer, such as linear low density polyethylene, is also obtained. -
Effect of fiber-matrix adhesion on the fracture behavior of a carbon fiber reinforced thermoplastic-modified epoxy matrix

In this study, the fracture behavior of a thermoplastic-modified epoxy resin reinforced with continuous carbon fibers for two levels of fiber-matrix adhesion was performed. A carbon fiber with commercial sizing was used and also treated with a known silane, (3-glycidoxy propyl trimethoxysilane) coupling agent. Toughness was determined using the double cantilever test, together with surface analysis after failure using scanning electron microscope. The presence of polysulfone particles improved... -
선형 및 분지화된 폴리카보네이트 블렌드의 기계적 성질과 유동특성
류민영, 이재식, 배유리 한국고분자학회 폴리머 10 Pages

본 논문은 선형 폴리카보네이트와 분지화된 폴리카보네이트를 블렌드한 시스템에 대해서 연구하였다. 여러가지 조성으로 두 성분을 블렌드하여 각 조성에 대해서 상용성, 기계적 성질 그리고 유동특성을 조사하였다. 본 블렌드 시스템에서 상분리는 관찰되지 않았고 상용성도 있었다. 기계적 성질은 블렌드의 각 조성에 대해서 인장강도, 굽힘강도 그리고 충격강도 등을 측정하여 검토하였으며, 흐름특성 역시 블렌드의 각 조성에 대해 용융점도, 저장탄성률 및 손실탄성률을 여러 온도에서 측정하여 검토하였다. 그리고 용융점도의... -
Study on lowering the percolation threshold of carbon nanotube-filled conductive polypropylene composites

Conductive polymer composites (CPCs) consist of a polymeric matrix and a conductive filler, for example, carbon black, carbon fibers, graphite or carbon nanotubes (CNTs). The critical amount of the electrically conductive filler necessary to build up a continuous conductive network, and accordingly, to make the material conductive; is referred to as the percolation threshold. From technical and economical viewpoints, it is desirable to decrease the conductive- filler percolation-threshold as...
