Since the last decade, hyperbranched polymers (HBPs) have gained wider theoretical interest and practical applications in sensor technology due to their ease of synthesis, highly branched structure but dimensions within nanoscale, a larger number of modified terminal groups and lowering of viscosity in polymer blends even at higher HBP concentrations. Many researchers have reported the synthesis of HBPs using different organic-based core-shell moieties. Interestingly, silanes, as organic-inorganic hybrid modifiers of HBP, are of great interest as they resulted in a tremendous improvement in HBP properties like increasing thermal, mechanical and electrical properties compared to that of organic-only moieties. This review focuses on the research progress in organofunctional silanes, silane-based HBPs and their applications since the last decade. The effect of silane type, its bi-functional nature, its influence on the final HBP structure and the resultant properties are covered in detail. Methods to enhance the HBP properties and challenges that need to be overcome in the near future are also discussed.
在过去十年中，超支化聚合物（HBP）因其易于合成、高度支化结构但尺寸在纳米范围内、大量可修饰的端基以及即使在较高HBP浓度下也能降低聚合物共混物的粘度，而在传感器技术中获得了更广泛的理论关注和实际应用。许多研究人员报告了使用不同的有机基核壳部分合成HBP。有趣的是，硅烷作为HBP的有机-无机杂化改性剂备受关注，因为与仅含有机部分的情况相比，它们使HBP的性能有了巨大提升，如提高了热性能、机械性能和电性能。本综述聚焦于过去十年中有机官能硅烷、基于硅烷的HBP及其应用的研究进展。详细阐述了硅烷类型、其双官能性质、对最终HBP结构的影响以及由此产生的性能。还讨论了增强HBP性能的方法以及在不久的将来需要克服的挑战。
