纳米技术在聚合物改性方面的研究进展

NEW ADVANCE IN THE RESEARCH OF NANOTECHNOLOGY ON THE POLYMER MODIFICATION

综述了国内外纳米技术在聚合物改性方面的最新进展。无机纳米粒子改性聚合物的方法包括:直接生成法、原位生成法、插层复合法和反相微乳液法,其中直接生成法简单易行,但解决不了纳米粒子的团聚问题,其余方法则可使纳米粒子均匀分散在聚合物中形成纳米复合材料。无机纳米粒子改性后的聚合物既具有突出的力学性能,又有许多功能性,综合了无机、有机、纳米材料的优良性能,在许多领域有广阔的应用前景。

Some new advances in the research of nanotechnology on the polymer modification are reviewed. The methods ofmodified polymer by using inorganic nanoparticles include the direct formation, in situ formation, intercalation compounding and the reverse phase microemulsion. Agglomeration of nanoparticles can not be treated easily with the method of direct formation used conveniently. But nanoparticles can be dispersed into polymers well to form composites by using the other methods. Inorganic-polymer nano-composites have excellent mechanical properties and many functions. It combines the excellent properties of inorganic compound, poly-mer and nanometer-sized materials, which has wide application prospect in many fields.
