Preparation of sunlight-driven self-healing superhydrophobic cotton fabrics
摘要
Abstract
In order to prepare superhydrophobic cotton fabrics with good self-healing properties,SA@PDA microspheres with core-shell structure were prepared by using stearic acid SA as core material and PDA as shell material.Then,the microspheres and PDMS were dip-coated on the surface of cotton fabric to prepare SA@PDA superhydrophobic cotton fabric.The SA@PDA core-shell microspheres and cotton fabrics were characterized by SEM,FT-IR and XPS.The photother-mal conversion performance,self-healing performance and friction resistance of SA@PDA super-hydrophobic cotton fabrics under simulated sunlight were studied,and the repair mechanism was discussed.The results show that the superhydrophobic cotton fabric coated with SA@PDA core-shell microspheres has good photothermal conversion performance,and the temperature rise is 40.9℃ after simulated sunlight irradiation.After losing superhydrophobicity,the cotton fabric can restore the superhydrophobic state after 30 min of light repair,and can be recycled for 6 times.The fabric also has good friction resistance,and loses superhydrophobicity after rubbing with sandpaper for 3 200 cm.The self-healing mechanism of SA@PDA superhydrophobic self-re-pairing cotton fabric is the rapid migration of stearic acid in SA@PDA core-shell microspheres under photothermal action.关键词
