Abstract

The recent interest in multifunctional materials with tailorable performances led to the formulation of novel polymer blends, with enhanced properties with respect to traditional plastics and showing economical advantages compared to the synthesis of new polymers. However, polymer blends are immiscible in most cases, and proper compatibilization is therefore needed to obtain an alloy with suitable performances. Beside the traditional compatibilization approaches (i.e., addition of graft or branched copolymers, reactive compatibilization), a novel technique has recently emerged, based on the insertion of micro- and nanostructured inorganic fillers within polymer blends.

Therefore, the aim of this review is to give an overview about the role played by nanofillers on the compatibilization of polymer alloys. A survey of the most important papers in literature on this topic will be presented, trying to correlate the microstructural features of nanofilled blends to their physical properties. After an introduction on the general aspects of polymer alloys in Chapter 1, the most relevant compatibilization strategies will be presented in Chapter 2, with particular emphasis on the compatibilization induced by micro- and nanostructured fillers. Chapter 3 will be focused on the nanofiller induced compatibilization, and several examples of thermoplastic, thermosetting and elastomeric nanofilled blends will be presented. Considering the increasing importance of biopolymers and of their blends in the modern industry, in Chapter 4 it will be shown how nanofiller induced compatibilization could be successfully applied also to bioplastics based alloys. Due to the recent environmental concerns on the polymer waste management and the difficulties in the plastics sorting operations, in Chapter 5 it will be demonstrated that nanomodification of recycled plastics can lead to blend recyclates with good compatibility and suitable physical properties. The key aspects of the nanofiller induced compatibilization in polymer blends and the future perspectives will be summarized in Chapter 6.

添加纳米填料对聚合物混合物相容性的影响
近年来,人们对具有可定制性能的多功能材料产生了浓厚的兴趣,这促使人们开始配制新型聚合物共混物。与传统塑料相比,这种共混物具有更强的性能,而且与合成新型聚合物相比具有经济优势。然而,聚合物混合物在大多数情况下是不相溶的,因此需要进行适当的相容,以获得具有合适性能的合金。除了传统的相容方法(即添加接枝或支化共聚物、反应性相容)外,最近还出现了一种新技术,即在聚合物共混物中加入微观和纳米结构的无机填料。本综述将概述纳米填料对聚合物合金相容所起的作用,并对有关这一主题的最重要文献进行调查,试图将纳米填料共混物的微观结构特征与其物理性质联系起来。在第 1 章介绍了聚合物合金的一般情况后,第 2 章将介绍最相关的相容策略,并特别强调微结构和纳米结构填料诱导的相容。第 3 章将重点介绍纳米填料诱导的相容,并举例说明热塑性、热固性和弹性纳米填料混合物。考虑到生物聚合物及其共混物在现代工业中的重要性日益增加,第 4 章将介绍如何将纳米填料诱导相容成功应用于生物塑料基合金。由于最近对聚合物废物管理的环境关注以及塑料分类操作中的困难,第 5 章将说明对回收塑料进行纳米改性可生产出具有良好兼容性和合适物理性质的混合回收料。第 6 章将总结纳米填料在聚合物共混物中诱导相容的主要方面以及未来展望。
