一种新型绿色可降解高弹性膜材料

本发明涉及膜材料研发制备技术领域，公开了一种新型绿色可降解高弹性膜材料，经过改性后的半纤维素与山梨醇相容性好，二者相互渗透，并紧密结合为一体，小分子会取代半纤维素大分子间的氢键结合，而与半纤维素大分子链以氢键的形式构成三维网络状结构，膜材料裂纹逐渐减少，膜变得柔软，进而改善成膜性能，有很强的弹性及延伸率，厚度低至0.05毫米，透明度高，拉伸强度17.1-17.5MPa，断裂伸长率达到了610-620%，具有环境友好、可降解等优良性质，生产工艺简单，原料来源丰富，生产成本低，具有良好的应用前景。 The invention relates to the technical field of membrane material research and development and preparation and discloses a novel green degradable high-elasticity membrane material. Modified hemicellulose has good compatibility with sorbitol, the two components infiltrate into each other and are tightly integrated, micro-molecules replace hydrogen bonding of hemicellulose macro-molecules, the micro-molecules and hemicellulose macro-molecule chains form a three-dimensional network-like structure in a hydrogen bond way, membrane material cracks are gradually decreased, a membrane becomes soft, thus the membrane formation performance is improved, the membrane has very high elasticity and ductility, the thickness is as small as 0.05 mm, the transparency is high, the te
