采用物理方法在高压下制备了酚醛树脂(PF)/累托石(REC)纳米复合材料,用X射线衍射(XRD)、透射电子显微镜(TEM)及热分析(DSC/TGA)等方法,研究了复合材料的物相、显微结构以及热学性能。结果表明,不通过层间高分子聚合反应,不预先对累托石进行有机化处理,在高压下,由聚合物分子插入粘土层间,可以形成剥离型树脂/粘土纳米复合材料,并且其热学性能发生了较大的改变。 Phenolic resin (PF) / rectorite (REC) nanocomposites were prepared by physical method under high pressure. The properties of the composites were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM) and thermal analysis (DSC / TGA) The composite phase, microstructure and thermal properties. The results show that the exfoliated resin / clay nanocomposites can be formed by intercalation of polymer molecules into clay layers without the prior organic treatment of the rectorite through interlamellar macromolecule polymerization, and the thermal Great changes have taken place in performance.
