摘要:本研究采用低共熔溶剂(DES,氯化胆碱/草酸)处理高得率浆(HYP),经抽滤、超声和热压处理后,制备了性能优良的木质纤维素膜(HYP/DES/HP膜)。探讨了热压条件对HYP/DES/HP膜的机械强度和疏水性能的影响。结果表明,在最优热压条件下(140 ℃、8 MPa、9 min),HYP/DES/HP膜的拉伸强度与水接触角分别可达16.24 MPa和87.9°,相较于未热压木质纤维素膜,分别提升了88.2%和74.4%。
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 under 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.
