Preparation and Properties of Polydimethysiloxane/Polycaprolactone/Epoxy Resin Composites
摘要
Abstract
A series of resin composites were prepared by blending epoxy and Silyl-terminated polypro-lactone/polydimethysiloxane (PCL-TESi/PDMS-TESi). The morphology and the surface element of composites system were investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy. Mechanical properties, water-resistance properties and thermal properties of the composites were also studied. The results showed that the morphologies, mechanical properties, water resistance properties and thermal properties of the composites were quite dependent on the content of PCL-TESi/PDMS-TESi. The Si element migrated toward surface to some extent. When mass ratio of PCL-TESi/PDMS-TESi and epoxy was 5 : 5, the mass change of composite is below 1% after soaked in distilled water at 50°C for 7 days, the elongation rate at break increased from 0% to 27% while tensile strength remain 23MPa, and in thermogravimetry analysis (TGA) , the characteristic decomposition temperature at 5% mass loss was evidently increased from 155. 8°C of pure epoxy to 310. 2℃.关键词
