摘 要：We put forward a large-area and cost-effective method to fabricate superhydrophobic coating by introducing in-situ functionalized nano-SiO2 into side-amino modified hydroxy-terminated polydimethylsiloxane（SA-HTPDMS） curing system. With the characterization using water contact angle（WCA） tester, Fourier transform infrared spectroscopy（FTIR）, scanning electron microscope（SEM）, atomic force microscopy（AFM） and simultaneous thermal analysis, the as-prepared coating displayed a tremendous WCA of 154.8±1°, sliding angle（SA） about 3.5° and stable self-cleaning property range from-10 to 80 ℃. It was also found that the synergistic effect of surface micro-nano hierarchical structure and chemical hydrophobicity, stability from matrix had made contributions to the superhydrophobicity and excellent heat resistance up to 300 ℃.
