Study on Preparation and Properties of Flexible Cellulose Composite Films
摘要
Abstract
A series of flexible cellulose composite films were prepared by the coating method using phytic acid(PA)as a cross-linking agent,with the incorporation of polyvinylidene fluoride(PVDF)and polyvinylpyrrolidone(PVP).The results showed that the composite films exhibited distinct infrared absorption peaks at 3 301,1 631,1 200 cm-1.Under microscopic observation,the films consisted of interlaced irregular elongated structures with rough surfaces and obvious pore structures,with porosity ranging from 42.2%to 14.5%,and a maximum tensile stress of 14.8 MPa.Among them,SF-2,introduced with 0.5 mL PA in 1.0 g PVDF and 0.5 g PVP,demonstrated relatively superior overall properties and good hydrophilicity,with a contact angle of approximately 43.2°,a maximum tensile stress of 13.25 MPa,a swelling ratio of 73.1%,and a pure water flux of 130.8 L/(m2·h).The adsorption performance was investigated using methylene blue and indocyanine green as dye models,with the adsorption capacities of 2 378.19 mg/kg and 9 312.18 mg/kg,respectively.The adsorption mechanisms for both dyes conformed to the pseudo-second-order kinetic model and the Langmuir adsorption isotherm.关键词
