Synthesis and micromechanical properties of flexible, self-supporting polymer-SiO2 nanofilms.

摘要: Large-scale, self-supporting ultrathin films composed of an elastomeric polyacrylate network interpenetrated by a silica (SiO2) were synthesized and characterized. The organic was first photopolymerized the structure subsequently developed in situ preformed gel. Composition morphology hybrid (IPN) nanofilms characterized infrared spectroscopy, X-ray photoelectron scanning electron microscopy, transmission microscopy compared with case zirconia (ZrO2) IPN reported earlier. Young modulus, ultimate tensile strength, elongation determined for different organic/inorganic molar ratios give some insights on how composition influence their robustness properties.
