In this study, biodegradable poly(p-dioxanone) (PPDO)/octamethyl-polyhedral oligomeric silsesquioxanes (ome-POSS) nanocomposites were fabricated by the simple solution casting method with various ome-POSS loadings. Scanning electron microscopic observations indicate that ome-POSS is well dispersed in the PPDO matrix. Effect of ome-POSS on the isothermal melt crystallization and dynamic mechanical properties of PPDO in the nanocomposites were studied in detail. It shows that the overall crystallization rates are faster in the nanocomposites than in neat PPDO and increase with the increase in ome-POSS loadings; however, X-ray diffraction patterns, POM and the Avrami exponent suggest that the crystal structure and the crystallization mechanism do not change despite the presence of ome-POSS. The mechanical property of PPDO/ome-POSS nanocomposites was enhanced with respect to neat PPDO.

The lotus leaf has the Janus wettability and outstanding floatability at multiphase interface. The ingenious design on lotus leaf surfaces enlightens us to fabricate the superhydrophobic/superhydrophilic binary cooperative membrane. Making use of the poor permeability of the candle soot, deposition of a layer of candle soot enables to form the Janus membrane with anisotropic wettability on different surfaces. After fixed by the hydrophobic polymer, the superhydrophobic/superhydrophilic binary cooperative membranes are prepared successfully on various membranes, such as filter paper, cotton fabric and copper mesh. The Janus membrane exhibits excellent interfacial floatability at the immiscible oil–water interface as a separator, thus affording high-performance immiscible oil/water separation without applied external pressure.
