Abstract


Polymer / Layered Silicate Nanocomposites than traditional composite modulus , excellent mechanical properties and thermal properties , good gas barrier and flame retardant properties , has attracted wide attention . In this paper, the study is a composite of P (AN-VAc-PMMT) . The experiment first synthesis of a polymerizable quaternary ammonium salt monomer PQA pMMT montmorillonite can participate in the polymerization reaction was prepared by ion exchange reaction . By X-ray verification instructions was successfully prepared pMMT . The experimental monomer mass ratio of the AN : VAC for 9:1 invariants by mass change PMMT , prepared by emulsion polymerization method P (AN-VAc-PMMT) composites . TEM and SEM characterization of the microstructure of the composite , and the intercalation structure type composite were analyzed by XRD , DSC analysis of the the composite thermal decomposition temperature changes . The results showed that the composite material P (AN-VAc-PMMT) increases the size of the nanospheres of about 150 nm , and the With increased PMMT content , the structure of the composite material , the thermal decomposition temperature of the transition from the peel -type structure to the plug -layer type . Experiment using an electrostatic spinning method of preparing the P (AN-VAc-PMMT) nanofibers , and discusses the influence of electrostatic spinning of various factors , and the results showed that in the case of the fixed receiver distance , the average diameter of the fibers increases with increasing voltage first decreases and then increases ; , the average fiber diameter in the case of a fixed voltage with the increase of the receiving distance decreases ; the average diameter of the fibers increases with the increase of the inner diameter of the capillary .
