Our work aims to investigate the morphology and properties of natural rubber (NR) dispersed in a polystyrene/silica hybrid nanomatrix. The hybrid nanomatrix structure was formed by the graft copolymerization of vinyltriethoxysilane onto NR grafted with styrene. This hybrid nanomatrix structure was composed of nanosilica with a size of less than 100 nm, and the incorporation of polystyrene resulted in outstanding mechanical and viscoelastic properties. The tensile strength of NR with the hybrid nanomatrix structure was 23 MPa, and the storage modulus was 2.54 MPa, which were 2.5 and 15 times higher than those of the silica nanomatrix. The outstanding mechanical and viscoelastic properties of this NR material were attributed to the formation of the hybrid nanomatrix structure. The roles of polystyrene and silica and their synergetic effect were clarified by investigating the morphology and properties of the hybrid nanomatrix after acetone extraction and annealing.

我们的工作旨在研究分散在聚苯乙烯/二氧化硅杂化纳米基质中的天然橡胶 (NR) 的形态和性能。杂化纳米基质结构是由乙烯基三乙氧基硅烷接枝共聚到接枝有苯乙烯的天然橡胶上形成的。这种杂化纳米矩阵结构由尺寸小于 100 nm 的纳米二氧化硅组成，聚苯乙烯的掺入导致了出色的机械和粘弹性能。具有杂化纳米基质结构的天然橡胶的拉伸强度为23 MPa，储能模量为2.54 MPa，分别是二氧化硅纳米基质的2.5和15倍。这种 NR 材料出色的机械和粘弹性能归因于混合纳米矩阵结构的形成。
