英文摘要： The applicant has been focusing on the preparation and application of functional polymers. A new idea on starch modification was proposed by introducing amphoteric semi-interpenetrating polymer network into starch matrix. Besides, this idea was also extended to the field of clay-based nanocomposite hydrogels, and mechanically strong amphoteric nanocomposite hydrogels with double networks was successfully prepared. In recent 5 years, the applicant took charge of 5 research projects, including 1 Program for New Century Excellent Talents in University and 3 National Natural Science Funds. She published 18 articles, of which 16 articles were SCI-cited and cited 82 times by others in SCI system (all SCI-cited papers were cited 8.4 times per paper within SCI system in 5 years, among which a paper was cited 43 times). 2 invention patents were authorized. 2 papers were awarded as Excellent Papers of Natural Science in Xinjiang Uygur autonomous region. She won second class award for Science and Technology Progress of Xinjiang Autonomous Region and first class award for Science and Technology Progress of Urumqi city. This project attempts to develop a silica-based intercalating and crosslinking agent. A mechanically-strong clay nanocomposite hydrogel is prepared by simultaneous synthesis of Sol-Gel and polymerization of hydrophilic monomers after intercalation. Relationship between intercalation method, as well as dual nanostructure and hydrogel properties is revealed. The work is an extension of previous distinctive research. This will take a new method for new organic-inorganic nanocomposite materials, and light clay industry development in Xinjiang.
