PLMA/PU共混纤维的制备与吸附性能
Preparation of PLMA/PU Blend Fiber and Its Absorption Properties
摘要
Abstract
Polylauryl methacrylate (PLMA) was synthesized via aqueous suspension polymerization using polyvinyl alcohol (PVA) as a dispersing agent and benzoyl peroxide (BPO) as an initiator.PLMA/PU (polyurethane) blend fibers were prepared via blending,pelleting and melt spinning.The structure and properties of the as-spun fibers were investigated by Fourier transform infrared spectrometer(FTIR),scanning electron microscopy(SEM),electronic tensile tester and optical contact angle measuring apparatus.We also studied the absorption rate and reusability of fibers.The results demonstrate that the as-spun fibers exhibit good hydrophobicity and lipophilicity,the fibers are obviously swollen after oil adsorption; the fibers have impressive oil absorbency for light organic liquids,the maximum oil absorbency are 4.86,8.1,2.42,2.04 and 3 g/g for toluene,trichloroethylene,diesel,kerosene and 10％ mass fraction of crude oil,respectively.The oil-absorptive fiber could be reused after adsorption-desorption.PLMA played a dominant role during adsorption process; PU played a skeletal role in both organic liquid adsorption and spinning.关键词
