摘要
Abstract
This study employed deep eutectic solvents(DES,choline chloride/oxalic acid)to treat high yield pulp(HYP).Following vacuum filtration,ultrasonication,and hot pressing,high-performance lignocellulosic films(HYP/DES/HP films)were prepared.The effects of hot-pressing conditions on the mechanical strength and hydrophobicity of the HYP/DES/HP films were investigated.The results showed that un-der optimum hot pressing conditions(140℃,8 MPa,and 9 min),the mechanical strength and water contact angle of the HYP/DES/HP film reached 16.24 MPa and 87.9°,respectively,representing increased of 88.2%and 74.4%compared to the lignocellulosic film without hot pressing.关键词
