水溶性含氟聚合物杂化纳米SiO2制备超疏水材料及性能.

In order to reduce the use of toxic organic solvents？ environmentally friendly water-soluble superhydrophobic materials were prepared. Waterborne epoxy resiri poly(glycidyl methacry 1 ate-random butyl acrylater andom-hydroxy et h y 1 meth aery late (「(GMA-r-ftA-r-HEM八))was prepared by radical polymerization heptafluorobutyric acid (HFBA) and riano-silica modified hybrid assembly, using water as solvent to prepare superhydrophobic materials, and superhydrophobic surface on cotton fabric surface. The hydrophobic properties and solvent resistance of cotton fabrics were investigated by changing the content of amino silica. The results show that the superhydrophobic effect of superhydrophobic treated cotton fabrics was better with the increase of amino silica content when the amount of grafted fluorine was constant. The cotton fabric impregnated with the super hyd rophobic material had a good lyophobic effect ？ the water contact angle was (1 50zh2)°, and the durability time was 83 niiri. It had good solvent resistance and could withstand water washing, ultrasonic and NaCO solution washing. [ABSTRACT FROM AUTHOR]
