聚电解质作为絮凝剂、驱油剂、分散剂、吸水剂、药物缓释等材料已被广泛应用于生态、能源、生物医药、功能材料等诸多领域。文中拟在着重介绍近年来聚电解质材料在水处理、石油开采、生物医用等方面最新进展的基础上,对其相关应用研究的发展趋势进行评述。
Polyelectrolyte has been one of the most important polymeric materials due to its water-soluble, charged and viscoelastic properties. As flocculant, polymer flooding reagent, dispersant, water-absorber and medical sustaining release material etc, it has been used in many fields such as ecology, energy, bio-medical and functional materials etc, which are most concerned issues by scientists today. Especially, as almost all the bio-macromolecules are polyelectrolytes, they have been playing more and more important role in biology. In this paper the latest progress of polyelectrolyte's applications in water-process, petroleum recovery, bio-medical areas were reviewed with 35 refs, and its future research was also predicted as a whole.
