Designing Photothermal Superhydrophobic PET Fabrics via In Situ Polymerization and 1,4-Conjugation Addition Reaction

Abstract

This study demonstrates a simple and fast method to integrate superhydrophobicity, UV protection, and photothermal effect onto PET fabrics. The surface of PET fabric forms a hierarchical rough structure through in situ oxidative polymerization of the pyrrole (Py). The 1,4conjugate addition reaction between pentaerythritol tetraacrylate, 3aminopropyltriethoxysilane, and octadecyl acrylate not only endows the PET fabric with superhydrophobicity but also forms a cross-linked network structure which improves the stability of multifunctional coatings on the surface of the PET fabric. In addition, the wettability of the prepared PET fabric is investigated by adjusting the Py monomer and octadecyl acrylate concentration. The results reveal that the prepared PET fabrics exhibit obviously superhydrophobic behavior with a contact angle of 155.8°. The surface temperature of the superhydrophobic PPy/PET fabric can rise to 91 °C under a simulated sunlight which is much higher than the pristine PET fabric, while reaching basically the same steady-state in five heating/cooling cycles. The prepared PET fabric also possesses excellent self-cleaning, UV shielding, and solar light absorption performances. Furthermore, the superhydrophobic PET fabric exhibited excellent stability against 180 °C high temperature, strong UV radiation, different pH solutions and organic solvent erosion, 8 h washing tests, and 25 sandpaper abrasion cycles. These findings provide a path for the future development of multifunctional fabrics using fluorine-free environmentally friendly materials.

A versatile “3M” methodology to obtain superhydrophobic PDMS-based materials for antifouling applications

“…The case of materials based on PDMS with nanoparticles is different from that of pure PDMS materials because nanoparticles possess inherently rough structures that can be directly exploited to fabricate PDMS-based superhydrophobic surfaces. Nanoparticle materials can be classified by morphology into four types: zero-dimensional nanoparticles ( He et al, 2011 ; He et al, 2012 ; Zhao et al, 2015 ; Aslanidou et al, 2016 ; Selim et al, 2018a ; Davis et al, 2018 ; Liu et al, 2018 ; Saharudin et al, 2018 ; Lu et al, 2019 ; Liu et al, 2020b ; Gu et al, 2020 ; Han and Gong, 2021 ; Xiong et al, 2022a ; Rin Yu et al, 2022 ; Yu et al, 2022 ) (such as spherical silicon dioxide (SiO 2 ) ( Aslanidou et al, 2016 ; Yu et al, 2022 ), titanium dioxide (TiO 2 ) ( Liu et al, 2020b ), polypyrrole nanoparticles ( Xiong et al, 2022a ), core-shell spherical composite nanoparticles ( Selim et al, 2018a ), or hollow spherical nanoclusters ( Han and Gong, 2021 )), one-dimensional nanoparticles ( Wang et al, 2019a ; Dai et al, 2019 ; Selim et al, 2019 ; Li et al, 2021 ) (such as linear nanorods ( Selim et al, 2019 ) and carbon nanotubes (CNTs) ( Li et al, 2021 )), two-dimensional nanoparticles ( Wang et al, 2019b ; Saharudin et al, 2019 ; Li and Guo, 2020 ; Cao et al, 2021 ) (such as laminar graphene and its derivatives ( Li and Guo, 2020 ), iron oxide (Fe 3 O 4 ) nanoplates ( Cao et al, 2021 )), and three-dimensional nanoparticles (single material nanoparticles such as tetrapod-shaped zinc oxide (ZnO) ( Yamauchi et al, 2019 ) and flower-like calcium titanium (CaTiO 3 ) structures ( Wang et al, 2007 ), and composite nanoparticles ( Nine et al, 2015 ; Shi et al, 2015 ; Barthwal et al, 2020 ; Zhu et al, 2020 ; Zhang et al, 2021a ; Zhang et al, 2021b ; Wu et al, 2021 ; Selim et al, 2022a ;…”

Polydopamine/SiO2 Hybrid Structured Superamphiphobic Fabrics with Good Photothermal Behavior

“…The superamphiphobicity refers to the contact angles of water (WCA) and oil on the surface greater than 150°. Superamphiphobic properties are widely used in self-cleaning, − anti-fouling, − anti-corrosion, , and other fields. − Therefore, in order to solve the above problems, we obtain self-cleaning photothermal materials by introducing superwettability.…”

Superhydrophobic Polyurethane Membrane with a Biomimetically Hierarchical Structure for Self-Cleaning

“…Besides, organic fluorine and silicon are two kinds of materials with the lowest surface energy in nature and concurrently are also commonly used together with structures for preparing superhydrophobic materials. 18 Usually, superhydrophobic materials can be categorized into three types: 1) low surface energy modification after construction of structures; 19 2) construction of structures after low surface energy modification; and 20 3) construction of structures and low surface energy modification simultaneously. 21 Different from the first two abovementioned methods, the process of the third method is simple, fast, and convenient.…”
