Abstract: To gain self-cleaning and anti-fouling properties, silk fabric surface was firstly coated with
polydopamine (PDA), prepared by polymerization of dopamine (DA) under CuSO 4/H 2O 2 oxidation system,
and then superhydrophobically functionalized by dodecyltrimethoxysilane (DTMS) modified nanoTiO 2.
The chemical composition, surface microstructure, and hydrophobic properties of silk fabrics before and
after modification were further characterized by FTIR, SEM, XPS, water contact angle measuring
instrument, followed by investigation on the performance of modified silk fabric in the aspects of
self-cleaning, anti-fouling, self-repairing of hydrophobicity and UV resistance. The results showed that the
silk fabric modified with PDA/DTMS-nanoTiO 2 exhibited uniform micro and nano structure, as well as
decreased surface free energy. The contact angle and rolling angle of modified silk fabric was 156° and 5°,
respectively, while the UV protection factor (UPF) was 75.81, indicating good anti-fouling self-cleaning
ability and UV resistance喑compared to original silk fabric. The silk fabric after modification displayed a
slight decrease in gas permeation. After 10 etching-repair cycles of O 2 plasma or 1200 mechanical
wear-repair cycles, the hydrophobic repair rate of the modified fabrics still remained >96%, demonstrating
good self-healing capacity from environmental damage. In addition, the modified silk fabric still retained
