Research development of gradient polymer materials

梯度高分子材料因其独特的结构、特殊的功能和潜在的应用价值,受到材料领域研究者的广泛关注。围绕高分子梯度材料的分类、制备方法和表征手段等展开调研,综述了共聚物型、填充复合型、共混型、互穿网络型等高分子梯度材料的种类,以及单体反应活性差异法、溶胀法、温度梯度场法、溶解扩散法、熔融挤出法、组分用量调控法、光场梯度法等制备方法,并对其表征方法进行了总结。在此基础上,展望了梯度高分子材料未来的研究和发展方向。

Polymer gradient material for its unique structure, special features and potential applications, has been widespread concerned. This paper summarizes the types of gradient polymer materials, such as copolymer, filling compound, blends and interpenetrating polymer network. The method of the difference of monomer reac- tivity, swelling method, temperature gradient method, dissolution-diffusion method, melt-extrusion method, component dosage control method and light field gradient method, as well as characterization ways of gradient polymer materials were also been reviewed in this work. Finally, the future research direction of gradient poly- mer materials was discussed.
