Abstract

Environmentally friendly biocomposites were prepared by blending wheat gluten(WG) as a matrix, hydroxyethyl cellulose(HEC) as a filler, and glycerol as a plasticizer, followed by thermo-molding of the mixture at 120 °C for crosslinking the matrix. Moisture absorption, tensile properties, dynamic mechanical analysis, and dynamic rheology were evaluated in relation to the glycerol content. Tensile strength and modulus drop dramatically with increasing glycerol content, which is accompanied by significant depression in the glass transition temperature and improvement in the extensibility of the biocomposites.

甘油含量对小麦面筋/羟乙基纤维素生物复合材料性能的影响

以小麦面筋(WG)为基体，羟乙基纤维素(HEC)为填料，甘油为增塑剂，在120℃下进行热成型，使基体交联，制备了环保型生物复合材料。吸湿性、拉伸性能、动态力学分析和动态流变学与甘油含量的关系进行了评估。随着甘油含量的增加，生物复合材料的拉伸强度和模量急剧下降，同时玻璃化转变温度明显降低，拉伸性能提高。
