Stable super-hydrophobic and comfort PDMS-coated polyester fabric

Abstract

Super-hydrophobic fabrics have shown great potential during the last decade owing to their novel functions and enormous potential for diver’s applications. Surface textures and low surface energy coatings are the keys to high water repellency. However, the toxicity of nanomaterials, long perfluorinated side-chain polymers, and the fragile of micro/nano-texture lead to the super-hydrophobic surfaces are confined to small-scale uses. Thus, in this article, a stable polydimethylsiloxane (PDMS)-coated super-hydrophobic poly(ethylene terephthalate) (PET) fabric (PDMS-g-PET) is manufactured via dip-plasma crosslinking without changing the wearing comfort. Benefiting from the special wrinkled structure of PDMS film, the coating is durable enough against physical abrasion and repeated washing damage, which is suffered from 100 cycles of washing or 500 abrasion cycles, and the water contact angle is still above 150°. This study promotes the way for the development of environmentally friendly, safe, and cost-efficient for designing durable superhydrophobic coatings for various practical applications.

Green Method for the Preparation of Durable Superhydrophobic Antimicrobial Polyester Fabrics with Micro-Pleated Structures

“…Consequently, the content of C-Si bonds increases. These results collectively indicate the successful adhesion of the PDMS-Ag nanocomposite coating to the fabric and the effectiveness of plasma in enhancing PDMS graft polymerization on the PET surface [ 49 ].…”

“…Following this step, the fabric was rinsed with deionized water approximately four to five times until no detergent residue remained. Subsequently, the fabric was dried at 60 °C and set aside [ 49 ].…”

Optical Behavior of Curcuminoid Hybrid Systems as Coatings Deposited on Polyester Fibers

“…There are a lot of studies in literature regarding methods of treating polyester surfaces in order to increase the hydrophobicity of surfaces [9,50,51]. Of these, sol-gel coatings are well known and intensively studied and, therefore, in the present work, by varying the silica network modifiers, it is expected that coatings with hydrophobic properties will be obtained (Figure 5).…”

Super-Hydrophobicity of Polyester Fabrics Driven by Functional Sustainable Fluorine-Free Silane-Based Coatings

“…As a matter of fact, fluorine and silicon finishing compounds are the most often used finishing agents [11,12]. In the past, despite their remarkable water repellent qualities, the most common industrial water-repellents contained perfluorooctanoic acid and perfluorooctane sulfonate, which were hard to breakdown and presented the risk of significant harmfulness and bioaccumulation [13][14][15]. For these reasons, their usage has been restricted, making critical the development of water repellents free of fluorine compounds.…”
