聚乳酸 (PEA) 是一种完全可生物降解的潜在替代品，可替代用于各种商品应用的石油基塑料。然而，加工性和成本方面的困难限制了该聚合物在市场上占据一席之地。目前的研究试图在不损害其固有的突出特性（如良好的机械性能和生物降解性）的情况下改变 PEA 的加工性能和成本。经过化学处理的香蕉纤维 (BF) 和有机改性纳米粘土 (cloisite 30B) 通过熔融混合方法作为增强填料加入到 PIA 基质中。各种硅烷偶联剂和NaOH已用于BF的化学改性，以改善与PIA大分子的界面相互作用。通过机械、热和可燃性特性评估了 BF 增强 PEA 生物纳米复合材料优化组合物的性能特征。此外，新开发的生物纳米复合材料已用于在工业条件下制备可生物降解的餐具。 (C) 2013 Elsevier Ltd. 保留所有权利。
Polylactic acid (PEA) is a completely biodegradable potential replacement for petroleum based plastics used for various commodity applications. However, difficulties in processability and cost restrict the polymer to clinch its niche in the market. Present investigation tried to modify the processability and cost of the PEA without compromising its inherent highlighted properties like good mechanical performances and biodegradability. Chemically treated banana fiber (BF) and organically modified nanoclay (cloisite 30B) has been incorporated as reinforcing fillers within the PIA matrix by melt mixing method. Various silane coupling agents and NaOH have been used for the chemical modification of BF to improve the interfacial interaction with PIA macromolecules. Performance characteristics of optimized composition of BF reinforced PEA bionanocomposite was evaluated through mechanical, thermal and flammability characteristics. Further, the newly developed bionanocomposite has been used for preparing biodegradable cutlery under industrial conditions. (C) 2013 Elsevier Ltd. All rights reserved.
