等离子体诱导接枝聚合制备超疏水纺织品及其机制研究

The fibers with superhydrophobic function can not only lessen the environment and energy problems caused by textiles washing, but also effectively protect the body from the damage of environmental pollutants; therefore, the research on superhydrophobic fiber is of great significance.In this project, we grafted polymerization of silicon monomer onto fabrics surface by low pressure RF and atmospheric pressure glow dielectric barrier plasma-induced to develop superhydrophobic textiles. Types of active particles in the plasma discharge system and its effect on polymerization were investigated. To reveal the differences in terms of initiating polymerization, the changes of free radicals concentration in different fiber surface with different reaction atmosphere plasma-induced were investigated. The method to improve the durability of the superhydrophobic fabric was researched. Through the systemic research, establish a new method for superhydrophobic textiles preparation, clarify the influence of polymerization silicon monomer with plasma-induced, clear the relationship between the performance of superhydrophobic textiles and graft polymerization product structure, reveal the plasma-induced graft polymerization reaction mechanism.These research results can take an important guiding role in the design and fabrication of superhydrophobic textiles.
