P(AN/VAc)/Clay纳米复合材料的制备及表征

PREPARATION AND CHARACTERIZATION OF P(AN/VAc)/CLAY BASED NANO-COMPOSITE

通过原位聚合方法制备了聚(丙烯腈-醋酸乙烯酯)/蒙脱土(P(AN/VA c)/C lay)纳米复合材料。通过TEM、X-R ay、IR、NM R、DSC、TG对其形貌、粒径、组成、结晶结构和热性能等进行了表征,结果表明,P(AN/VA c)/C lay纳米复合材料的粒径尺寸为50 nm^80 nm,并呈多片层结构,clay片层均匀分布于P(AN/VA c)基体中,其耐热性均优于P(AN/VA c)。

P（AN/VAc）/Clay was preparated by in-situ polymerization in this paper. The superficial appearance, particulate dimension, compose, crystallizing structure and hot behavior of the composite were proved through TEM, X-ray, IR, NMR, DSC, TG. The results indicate that the particulate dimension of the nano-composite is 50 nm～80 nm, which belongs to nanometer, and the composite has multi-layer structure. The results also show that intensity, stability of dimension and heat-resistant property of P（AN/VAc）/Clay are all superior to that of P（AN/ VAc）, which is signifieative for polyacrylonitrile fiber or acrylic fiber.
