| 中文摘要 | a series of linear polyurethane (pu) elastomers containing various amounts (ca. 2-10 wt%) of a diol-functionalized polyhedral oligomeric silsesquioxane (diolposs) were synthesized from organic solvent dispersions. fourier transform infrared spectroscopy was used to characterize the chemical structure of the diolposs-reinforced pu. transmission electron microscopy (tem) indicated that the diolposs aggregation was formed in the polymer matrix at the scale of 20-50 nm. the introduction of diolposs into such system led to high glass transition temperature, enhanced storage modulus, and improved stability compared with the pristine pu according to the differential scanning calorimetry, dynamic mechanical analysis, and thermal gravimetric analysis, respectively. moreover, contact angle measurements indicated a significant enhancement in surface hydrophobicity as well as a reduction in surface free energy after introducing diolposs into the synthesized pu. the improvement of surface properties could be ascribed to the enrichment of the diolposs moiety on the surface of the hybrids. polym. eng. sci., 51:795-803, 2011.
