The invention discloses a method for preparing a superhydrophobic cotton
textile by
thiol-ene
click chemistry modification. The method comprises the following steps of Step 1, pretreating cotton fabrics so that
thiol groups are introduced to the
fiber surfaces; Step 2,
grafting thiol silane onto the surfaces of the pretreated cotton fabrics; and Step 3, soaking the cotton fabrics grafted with thethiol
silane into a
mixed solution prepared from
ethyl acetate, 2,4,6,8-Tetravinyl-2,4,6,8-tetramethylcyclotetrasiloxane, octadecanethiol and
benzoin dimethyl ether to take a reaction through UV
irradiation, and after the reaction is completed, performing cleaning and
drying to obtain the superhydrophobic cotton
textile. The invention also discloses the superhydrophobic cotton
textile prepared bythe method. The superhydrophobic cotton textile prepared by the method provided by the invention has the advantages that hydrophobic substances are grafted onto the surfaces of the fabrics in a
chemical bond form; and the performance of resisting acid, alkali,
water washing, friction, UV
irradiation and the like of the superhydrophobic textiles can be improved.
