Studies on Gel-spinning of Chitosan Dispersion Carbon Nano-tubes/polyacrylonitrile Composite Fibers
摘要
Abstract
After being treated by chitosan derivatives,the multi-walled carbon nano-tubes (MWNTs) were composited with ultimate high molecular weight polyacrylonitrile (UHMW-PAN).And then spin a series concentration of MWNTs proportion of MWNTs/PAN composite fibres via gel-spinning.Study on the effect of different methods of spinning,and the different proportion of multi-walled carbon nano-tubes on the tensile strength,modulus,orientation,crystallization structure.And the dispersion of MWNTs in PAN was observed by scan electron microscope.The result shows that:compared to wet-spinning fibers,the gel-spinning fibers have better orientation,dispersion,tensile strength and modulus.And the composited with carbon nano-tubes would engender the impact of sonic orientation of the fibers.While the mass fraction of MWNTs is 0.5%,compare to the PAN fibers,the tensile strength increase 37%,Young's modulus increase 11.68%,and the degree of sonic orientation is highly maintained (92.5%).关键词
