Abstract

The use of nanocomposites is regarded as a promising strategy to significantly improve the overall performance of polymeric materials using a minimal amount of additives. Recently, environmental pollution issues caused by discarded plastic waste have encouraged manufacturers and researchers to replace petroleum-based non-degradable plastics with biomass-derived degradable plastics. Recent research interest in polymeric nanocomposites has resulted in the development of biodegradable nanocomposites using bio-derived nanofillers. Cellulose nanocrystals (CNCs) are one of the most fascinating and widely investigated reinforcing fillers derived from biomass sources such as plants. Compared with conventional inorganic fillers, including carbon nanotubes and metal nanoparticles, CNCs are the most abundant renewable materials on Earth. They do not result in biodegradability deterioration when incorporated into biodegradable polymers. In addition, CNCs exhibit superior dispersibility and chemical affinity to polymeric matrices, resulting in better reinforcing efficiency. Accordingly, considerable effort has been devoted to achieve the desired processability, rheological behavior, and final performances of CNC-loaded nanocomposites. This review aims to provide an overview of the effects of CNCs on the processing, physical properties, and rheology of various types of polymer nanocomposites.

纤维素纳米晶增强聚合物纳米复合材料的研究进展:工艺、性能和流变学

纳米复合材料的使用被认为是一种很有前途的策略，可以显著提高聚合物材料的整体性能，使用少量的添加剂。近年来，废弃塑料垃圾造成的环境污染问题促使制造商和研究人员用生物质衍生的可降解塑料取代石油基不可降解塑料。近年来对高分子纳米复合材料的研究兴趣导致了生物来源纳米填料的可生物降解纳米复合材料的发展。纤维素纳米晶体(CNCs)是从植物等生物质来源中提取的最具吸引力和被广泛研究的增强填料之一。与碳纳米管和金属纳米颗粒等传统无机填料相比，cnc是地球上最丰富的可再生材料。当掺入生物可降解聚合物时，它们不会导致生物可降解性恶化。此外，cnc具有优异的分散性和对聚合物基质的化学亲和力，从而具有更好的增强效率。因此，为实现cnc负载纳米复合材料所需的可加工性、流变行为和最终性能，人们付出了相当大的努力。本文旨在概述cnc对各种类型的聚合物纳米复合材料的加工、物理性质和流变性的影响。
