The preparation of polyolefin composites using inorganic fillers is one of the most important strategies for cost reduction and property enhancement. The use of inorganic filler-supported catalysts for in situ polymerization to prepare polyolefin composites represents an effective strategy to address the non-compatibility issue. In this contribution, we design a borane cocatalyst-supported strategy to prepare heterogeneous catalysts supported on a series of nano-fillers such as SiO₂, Al₂O₃, TiO₂, MgO and ZnO. The in situ ethylene polymerization can produce ultra-high molecular weight polyethylene (UHMWPE) composite materials with excellent mechanical properties, thermal conductivity and surface properties. These polyolefin composite materials also exhibit efficient photodegradation capability, enabling sustainable application of these composite materials.

B(C6F5)3接枝无机填料用于负载钛催化合成UHMWPE复合材料

使用无机填料制备聚烯烃复合材料是降低成本和增强性能的最重要策略之一。使用无机填料负载的催化剂进行原位聚合制备聚烯烃复合材料是解决不相容性问题的有效策略。在这篇文章中，我们设计了一种硼烷助催化剂负载的策略来制备负载在一系列纳米填料（例如SiO ₂、Al ₂ O ₃、TiO ₂、MgO和ZnO）上的多相催化剂。乙烯原位聚合可生产具有优异机械性能、导热性能和表面性能的超高分子量聚乙烯（UHMWPE）复合材料。这些聚烯烃复合材料还表现出高效的光降解能力，使这些复合材料的可持续应用成为可能。
