高热稳定性聚膦腈亚微米球的室温快速合成
Rapid Room Temperature Synthesis of Polyphosphazene Sub-micrometer Spheres with High Thermal Stability
摘要
Abstract
Polyphosphazene(PPZ) sub-micrometer spheres were prepared rapidly under room temperature via precipitation polymerization of hexachlorocyclotriphosphazene ( HCCP) with 4, 4'-sulfonyldiphenol ( BPS) , using acetonitrile as the solvent and triethylamine (TEA) as the acid-acceptor. The PPZ sub-micrometer spheres were characterized by FT-IR, elemental analysis and EDX, and their highly cross-linked structures were identified. SEM and TEM results indicated that the PPZ sub-micrometer spheres had diameter of about 410 nm, solid structure and smooth surface. TCA result showed that the thermal decomposition temperature of the PPZ sub-micrometer spheres was about 531 t. In addition, the formation mechanism of the PPZ sub-micrometer spheres was proposed.关键词
