Nylon 6/Poly(p-phenylene terephthalamide)분자복합재료
Molecular Composite Nylon 6/Poly (p-phenylene terephthalamide)
초록
Nylon 6/PPTA 블렌드의 용융점도 및 shear thining 효과는 PPTA 함량이 증가할수록 증가하였다. 이러한 거동은 고상의 stiff한 PPTA 분자 혹은 microfibril의 존재에 기인되었다. Capillary rheometer을 이용하여 블렌드로부터 섬유(filament)를 제조한 결과 섬유내에서 PPTA상이 섬유축 방향으로 배향되어 있었다. Nylon 6/PPTA 섬유의 저장탄성율은 전단속도의 증가에 따라 증가하였으며, 섬유의 인장탄성율 및 강도는 PPTA 함량이 증가할수록 급격히 증가하였다. 강도 및 탄성율의 높은 값은 PPTA의 microfibril의 크기 및 배향에 기인되는 것으로 나타났다.
The melt viscosity and shear thining effect for nylon 6/PPTA blends increased markedly with increasing PPTA content. This is attributed to the existence of solid-like state stiff PPTA molecules or microfibrils. Filaments from the blends were obtained using a capillary rheometer. The PPTA phase in the filament prepared in this investigation exhibited well developed and oriented microfibrillar structure. The storage modulus for nylon 6/PPTA filament increased with increasing shear rate. The tensile modulus and strength of the filaments increased with increasing PPTA content. Higher values of strength and modulus were in part due to the fineness of microfibril and its orientation.
