生物可降解聚碳酸丁二醇酯改性的研究进展
Research Progress in Modifications of Biodegradable Poly(butylene carbonate)
二氧化碳下游产物碳酸二甲酯的规模化生产极大程度地促进了可降解聚碳酸酯的生产和使用,可有效利用二氧化碳并缓解塑料污染。因此,文章对当前新型生物可降解脂肪族聚碳酸丁二醇酯(PBC)的改性研究进展进行综述,着重分析共聚单体分子结构(线型脂肪族、环状脂肪族、芳香族单体)以及共混相容性影响脂肪族聚碳酸酯PBC的热性能、结晶性能以及力学性能作用机制,并基于PBC基共聚碳酸酯以及PBC基共混材料的结构与性能关联体系对其适用领域和发展趋势进行展望。
The production and application of biodegradable polycarbonate have been significantly facilitated by the scale production of dimethyl carbonate which is the downstream of carbon dioxide. Hence, the progress in current research of novel biodegradable aliphatic poly(butylene carbonate) (PBC) modification has been reviewed. The mechanism of monomer structure (i.e. linear aliphatic monomer, cyclic aliphatic monomer, and aromatic monomer) and blending compatibility effect on thermal properties, crystallization, and tensile properties of PBC were analyzed. In addition, the application and development were also prospected according to the structure-properties relationship of PBC-based co-polycarbonate and PBC-based blends.
