Abstract: Disclosed are a fluorine-silicon-containing polyphosphate ester and method for preparation thereof, having a chemical structural formula of: wherein R 1 is R 2 is n=10˜100. The fluorine-silicon-containing polyphosphate ester of the present invention uses silicon phosphorus and fluorine for improving flame retardancy. Phosphorus catalyzes the system to form a phosphorus-rich carbon layer, performing a protective-layer function and thereby preventing further breakdown of the epoxy resin. The silicon-containing epoxy resin forms a silica-containing carbon layer during the process of combustion, strengthening the carbon-layer structure and further improving the protective function of the carbon-layer. The introduction of elemental fluorine improves the thermal stability of the epoxy resin, thereby improving the flame retardancy performance of the system.

Abstract: Disclosed is a method for inducing orderly arrangement by means of polymer crystallization, and the use thereof in preparing a composite film. Firstly, monodisperse PS-DVB nano-microspheres of different sizes are prepared by means of soap-free emulsion polymerization; the PS-DVB nano-microspheres prepared above are used as raw material, and PEG aqueous solutions with different concentrations are added to induce an orderly arrangement of the nano-microspheres by means of solution-state PEG crystallization; and characterized by using scanning electron microscopy and polarizing microscopy. The method is simple in terms of operation and is widely applicable. By further modifying the orderly arrangement of the nano-microspheres, the composite material can be applied to different fields. The replacement of a substrate for crystalline polymer which inducing the orderly arrangement of the nano-microspheres enables the nano-composite material to become a thin film material or a bulk material modified and reinforced by the nano-microspheres.
