The application belongs to the technical field of textile fabric functional finishing, and particularly relates to a preparation method of super-hydrophobic fabric. The preparation method of the super-hydrophobic fabric comprises the following steps: pretreating cotton fabric by using a zinc ion mixed solution of sodium hydroxide to obtain cotton fabric containing a zinc oxide seed layer; then immersing the cotton fabric containing the zinc oxide seed layer in a mixed solution of a zinc nitrate aqueous solution and a hexamethylenetetramine aqueous solution to obtain a ZnO composite fabric; and finally using the bridging effect of a mercapto silane coupling agent to bond low-surface-energy polydimethylsiloxane and octavinyl octasilsesquioxane to the cotton fabric to obtain the super-hydrophobic fabric. The above method can endow the fabric with excellent hydrophobicity and improve the washing resistance of the hydrophobic effect.

This invention discloses a GTR membrane, its preparation method, and its application, belonging to the field of biomedical materials technology, and solves the problem of insufficient antibacterial effect of existing GTR membranes. The method includes the following steps: uniformly dispersing BaTiO3 in a Tris buffer solution; dissolving dopamine hydrochloride powder in the reaction system; stirring evenly; centrifuging to collect the precipitate; cleaning and drying to obtain PDA@BaTiO3 nanoparticles; adding the PDA@BaTiO3 nanoparticles to a silver ammonia solution; stirring at room temperature; centrifuging to collect the precipitate; cleaning and drying to obtain Ag@PDA@BaTiO3 particles; uniformly dispersing the Ag@PDA@BaTiO3 particles in a hexafluoroisopropanol solution of L-polylactic acid; electrospinning the reaction system to obtain a fiber membrane; and sequentially subjecting the membrane to ventilation, high-temperature annealing, and natural cooling to room temperature to obtain the GTR membrane. The GTR membrane provided by this invention possesses both piezoelectric and photothermal effects, exhibits rapid sterilization and long-lasting antibacterial activity, and has a simple preparation process.
