Özet

Boric acid particles were successfully prepared by using an emulsion liquid membrane (water-in-oil-in-water, W/O/W emulsion) to control the size of particles as raw materials. All materials aggregated in aqueous suspension, but their subsequent dispersion on treatment with the polyimide precursor, poly (amic acid), was observed. Using a combination by dissolving the polyimide and mixing fatty acid surfactant coated boric acid particles; we have demonstrated the formation of nanocomposites with uniform nanoparticle dispersion. The influence of boric acid on heat releasing capacity was analyzed. Heat releasing capacity of composites was reduced compared to polyimide itself The microstructures and morphology of the as obtained samples were studied by X-ray diffraction (XRD), infrared spectra (IR), scanning electron microscopy (SEM) equipped with an energy-dispersive X-ray spectrometer (EDS) and thermogravimetric analysis (TGA).
