天然橡胶(NR)及其衍生物因其独特的性能和广泛的应用而在各个行业中发挥着不可或缺的作用。然而,NR的广泛使用面临着固有的挑战,如有限的机械强度,耐热性和耐有机溶剂性差,导电性差,与其他材料的兼容性低,促使研究人员探索提高其性能。修饰的NRs(MNRs)如环化,脱蛋白,氯化,环氧化,或接枝NR与NR相比表现出一些增强的优点。然而,各种策略,比如混合,硫化,交联,嫁接,塑化,钢筋,和纳米结构,克服了大多数缺点。这篇综述全面研究了这些挑战,并深入研究了用于增强NR及其衍生物的性能和扩展应用的改性策略。此外,这篇评论探讨了NR行业的未来愿景,强调整合先进的改性技术,采用可持续的做法,推广循环经济原则。通过阐明内在的挑战,概述有效的修改策略,设想未来的轨迹,这项审查为寻求导航和促进NR部门可持续发展的利益相关者提供了宝贵的见解。
Natural rubber (NR) and its derivatives play indispensable roles in various industries due to their unique properties and versatile applications. However, the widespread utilization of NR faces intrinsic challenges such as limited mechanical strength, poor resistance to heat and organic solvent, poor electrical conductivity, and low compatibility with other materials, prompting researchers to explore enhancing its performance. Modified NRs (MNRs) like cyclization, deproteinization, chlorination, epoxidation, or grafting NR demonstrated a few enhanced merits compared to NR. However, various strategies, such as blending, vulcanization, crosslinking, grafting, plasticization, reinforcement, and nanostructuring, overcame most drawbacks. This
review comprehensively examines these challenges and delves into the modification strategies employed to enhance the properties and expand the applications of NR and its derivatives. Furthermore, the
review explores future visions for the NR industry, emphasizing integrating advanced modification techniques, adopting sustainable practices, and promoting circular economy principles. By elucidating the inherent challenges, outlining effective modification strategies, and envisioning future trajectories, this
review provides valuable insights for stakeholders seeking to navigate and contribute to the sustainable development of the NR sector.
