Some nanoparticles(for example, NiS and FePO4 particles) could he easily obtained by this method with high yield. The nanoparticles as prepared show good dispersion and narrow size distribution. The influence of the surfactant has been discussed.展开更多

Th e preparation conditions were studied and optimized. Nanosized Sb2O3 has been ch aracterized by means of XRD, TEM, FTIR. FTIR results show that IR absorption of nanosized Sb2O3 is red-shifted and strengthened. Microwave can promote the forma tion of nanosized Sb2O3. The concentration of urea affects particle size greatly . The nanosized Sb2O3 was applied to flame retarding polyethylene (PE)/ethylene-vinyl acetate copolymer (EVA) foams. The mechanical properties and flame retarda ncy of the flame retarding PE/EVA foams were much improved.展开更多
