摘　　要：纤维素作为一种生物可降解的可再生天然高分子化合物,在合成塑料制品替代方面拥有巨大的潜力。然而,与大多数石化类塑料高分子不同,纤维素分子链存在分子链间/分子链内氢键难以在常规条件下实现分子链间自由运动或滑移,进而在热塑性加工与利用方面面临诸多的挑战。基于此,从纤维素物化结构特点出发,深入讨论了纤维素凝聚态结构对其塑性加工的影响机理,探讨了纤维素增塑机理及相关技术发展特点及亟需解决的关键科学问题,对生物质基代塑加工技术进行了展望。Cellulose,as a biodegradable and renewable natural polymer,holds immense potential as an alternative to synthetic plastic products.However,unlike most petrochemical polymers,the inter-and intra-molecular hydrogen bonds of cellulose molecules hinder free movement or slippage between molecular chains under conventional conditions,which is a challenge problem in thermoplastic processing and utilization.In this article,the physicochemical structural characteristics of cellulose are summed,the affecting mechanisms are deeply discussed based on the condensed state structure of cellulose to plastic processing,the cellulose plasticization,technological development and key scientific issues are summarized.It also outlooks the advancement of biomass-based plastic substitute processing technologies.
