Fabrication of Superhydrophobic and UV-Resistant Silk Fabrics with Laundering Durability and Chemical Stabilities

Abstract

To obtain a superhydrophobic surface, SiO2 nanoparticles are deposited on the surface of silk fabric (SF) by Plasma Enhanced Chemical Vapor Deposition (PECVD) to form a hierarchical roughness structure. In addition, a durable superhydrophobic SiO2@silk fabric was further prepared by hexamethyldisilazane (HMDS) modification. Compared with bare silk, the surfaces of the SiO2@silk fabric exhibit higher surface roughness and excellent superhydrophobic activity, with a contact angle (CA) of ~152°. The excellent UV resistance of SiO2@silk fabric was confirmed with high UV protection factor (UPF) values and a low UV transmittance. Moreover, both the laundering durability and chemical stability of the SiO2@silk fabric were improved. Overall, this method is recognized as a promising approach to produce high-end fabric development. It can also guide the design of multifunctional fiber materials in the future.

Superhydrophobic Non-Metallic Surfaces with Multiscale Nano/Micro-Structure: Fabrication and Application

“…CVD mainly uses one or several vapor compounds or elements containing thin-film elements to chemically react together on the surface of substrate to produce a thin film [45,125]. Commonly used deposition materials include carbon nanotubes [126,127], SiO 2 [128,129], TiO 2 [130], PDMS [131,132] and so on. For example, Tombesi et al [133] used aerosol-assisted chemical vapor deposition (AACVD) to fabricate SiO 2 nano-particle films with dual-scale roughness on glass substrates.…”

Enhancement of natural dyeing properties and UV resistance of silk fibers modified by phenylboronic acid/hydroxypropyl‐β‐cyclodextrin functionalized Fe3O4 particle

“…The color strength ( K / S value) under illuminant D65 were automatically calculated 47 . The ultraviolet protection factor (UPF), ultraviolet transmittance rates T UVA , T UVB was measured using UV‐912E tester (Wenzhou Da Rong Textile Instrument Co., Ltd., China) 2,48 . The stress–strain curves of the untreated and modified silk fabrics (2 cm × 10 cm) were measured three time on electromechanical universal testing machine (CMT4304, MTS SYSTEMS CO, LTD, China) to attain the average value with a gauge length of 100 mm and a strain rate of 10 mm/min under the condition of 20°C and 40% RH.…”

The light, washing and rubbing fastness of dyed silk fabrics were tested according to GB/T 8427-2008, ISO 105-C06, and ISO 105-X12, respectively.…”

Effects of Ultraviolet Light Irradiation on Silk Fibroin Films Prepared under Different Conditions

“…For several decades, many researchers have tried to understand the UV-induced photo-aging process of silk fabrics, solutions, and films. The accumulated results have demonstrated that SF fiber is susceptible to UV-induced changes in color and brightness [ 10 , 11 ] because SF molecules contain numerous aromatic amino acids such as tyrosine (5.1%), tryptophan (0.1%), and phenylalanine (0.4%) [ 8 ]. In addition, it is revealed that photo-destruction of the ordered structures by UV irradiation makes silk fibers more brittle than those that are nontreated [ 12 ].…”
