Research progress on the improvement strategy of foaming behavior for biodegradable polymer foams and their functional applications
Biodegradable polymer foams have attracted extensive attention due to their advantages, like non-polluting degradation products, green environmental protection, light weight and high toughness. However, the foaming behavior of biodegradable polymer foams is difficult to regulate because of restriction by the crystallinity and melt strength of biodegradable polymers, which in turn affects performance stability and constrains their practical application. Accordingly, this study focuses on the strategies of foaming method, compositing filler and blending polymer to improve the foaming behavior of biodegradable polymer foams. The corresponding improvement mechanism for each strategy is analyzed and summarized in detail. Besides, the functionality and application fields of biodegradable polymer foams are also summarized. Finally, the future research direction of biodegradable polymer foams is proposed. This review aims to provide guidance for the study of cell structure regulation and performance expansion of biodegradable polymer foams.
期刊介绍:
Sustainable Materials and Technologies (SM&T), an international, cross-disciplinary, fully open access journal published by Elsevier, focuses on original full-length research articles and reviews. It covers applied or fundamental science of nano-, micro-, meso-, and macro-scale aspects of materials and technologies for sustainable development. SM&T gives special attention to contributions that bridge the knowledge gap between materials and system designs.
