纳米粒子的尺寸介于体相材料和分子之间,具有许多独特的物理和化学性质,近年来在催化、光电子以及生物等领域得到广泛的关注.为了使纳米粒子更好的展现它们特有的功能,将其与聚合物复合是行之有效的方法,这不仅可以稳定纳米粒子,还可以实现纳米粒子与聚合物之间功能的集成.但是,这一思想的实现在很大程度上依赖于纳米粒子与聚合物之间的相容性,以及如何调节纳米粒子与聚合物之间的相互作用,使我们得到预期的功能.因此,人们发展了许多将纳米粒子复合到聚合物中的方法.本文主要阐述了近几年我们课题组把原位法和其他方法有机结合,实现纳米粒子与聚合物的复合,从而制备了具有不同功能的一维、二维乃至体相纳米粒子/聚合物复合材料.我们所建立的这些方法最突出的特点是纳米粒子与聚合物之间具有很好的相容性,可以确保其在聚合物中的均匀分散,而且聚合物网络结构的存在使纳米粒子更加稳定,对于更好的体现其功能具有重要意义.
Nanomaterials have many unique physical and chemical properties, which are between the bulk materials and molecules, and have attracted a great deal of attention in catalysis, optoelectronics and biology in recent years.In order to make the nanoparticles better display their unique functions , It is an effective method to compound with polymers, which can not only stabilize the nanoparticles, but also realize the functional integration between the nanoparticles and the polymers.But the realization of this idea relies heavily on the nano The compatibility between particles and polymers, and how to tune the interaction between nanoparticles and polymers, give us the expected function. Thus, many methods have been developed to incorporate nanoparticles into polymers. In the last several years, our group mainly combined the in-situ method with other methods to realize the composite of nanoparticles and polymers, thus prepared one-dimensional, two-dimensional and even bulk nanoparticles / polymer composites with different functions The most striking feature of these methods we have built is the good compatibility of the nanoparticles with the polymer to ensure that it is in the polymer Uniformly dispersed, and the presence of the polymer network structure the nanoparticles more stable to better reflect their function is important.
