用超声法制备膨胀石墨纳米片，使其均匀分散在不饱和聚酯树脂中。然后用固化剂将分散体置于电场中，然后进行交联，以制备聚合物/GN复合薄膜。x射线衍射和扫描电镜显示，薄膜中的GNs取向与电场平行。紫外可见测试表明，与没有电场的复合膜相比，场致复合膜的可见光透过率有显著提高。(c) 2007年Elsevier Ltd.出版
Graphite nanosheets (GNs) prepared by sonicating expanded graphite were homogeneously dispersed in unsaturated polyester resin using sonication. The dispersion with a curing agent was then subjected to a de electric field, followed by crosslinking, to fabricate a polymer/GN composite film. X-ray diffraction and scanning electron microscopy revealed that the GNs in the film were oriented parallel to the electric field. UV-VIS measurements indicated that the optical properties of the field-induced composite film showed significant improvement in visible light transmittance compared with those prepared without the electric field.
