| Abstract: | The benzoxazine/incomplete trisilanol POSS mixtures were prepared by solvent method, and the corresponding composites were obtained after curing. The structures, curing behavior and thermal properties were characterized by FTIR, X-ray diffraction, DSC, DMA and TGA. The results showed that chemical bonds have been formed between trisilanolphenyl POSS and PBZ, and trisilanolphenyl POSS possessed better compatibility with the matrix than trisilanolisobutyl POSS; the dynamic viscoelastic properties and thermal stability of the composites have been greatly enhanced by the incorporation of trisilanolphenyl POSS. However, the improvements on the dynamic viscoelastic properties of PBZ/trisilanolisobutyl POSS were not so markedly. |
