A Facile Modifier-free Approach to Fabricate Antistatic Superhydrophobic Composite Coatings with Remarkable Thermal Stability and Corrosion Resistance

Abstract

Research on antistatic superhydrophobic surfaces has attracted widespread attention in some fields. However, in the application of superhydrophobic materials, fabricating stable and practical superhydrophobic surfaces through facile and low-cost approaches still faces considerable challenges. Herein, a polyphenylene sulfide (PPS)-based antistatic superhydrophobic composite coating with a high water contact angle (166°) and a low sliding angle (2°) was fabricated on a Q345 steel surface through a simple spray-coating method without any modifier. Furthermore, the as-prepared superhydrophobic coating also displayed excellent superhydrophobicity for water droplets at different pH values, as well as self-cleaning, anti-fouling and anti-icing properties. Importantly, the superhydrophobic coating still exhibited superhydrophobicity after calcination at 350 °C for 1 h, indicating its outstanding thermal stability. Excellent antistatic and anticorrosion properties were obtained on the prepared coating surface, which allows the coating to be applied under harsh conditions. Benefiting from the above characteristics, compared with the commercial coating, the as-obtained antistatic superhydrophobic coating may be applied more widely in related fields.

Stable and Durable Conductive Superhydrophobic Coatings Prepared by Double-Layer Spray Coating Method

“…The corresponding element distribution on the CSC coating surface is displayed in Figure 3d, and it can be seen that elements of various additives are distributed on the coating surface. According to our previous work [33], the EDS spectrum of the obtained CSC coating surface is shown in Figure 3e and it can be easily seen that the CSC coating is composed of C, O, F, Si, Ce, and S. Additionally, the peaks of the F, Si, Ce, and S were attributed to the presence of PTFE, PDMS, CeO 2 , and PPS in the MSC coating, respectively. Figure 3b exhibits the corresponding schematic diagram of superhydrophobicity.…”

“…Tetrapropylammonium bromide (TPAB) was obtained from the Sinopharm Chemical Reagent Co. Ltd (Shanghai, China). According to our previous work [33], 3D flower-like CeO 2 particulates were synthesized with a simple procedure. PPS (average Mn: 1 × 10 4 , yellow color powder) was purchased from Sigma-Aldrich Co. Ltd (Saint Louis, MI, USA).…”

The Study on the Anti-corrosion Performance of NiTi Alloy in Human Body Solution with the Fabricating Processes of Laser Irradiation and PDMS Modification

“…Inspired by bionics, fabricating super-hydrophobic surface on materials has been regarded as an admirable technology of excellent anti-corrosion performance [9,10] . Previous literatures have demonstrated that the real contact area between super-hydrophobic interface and corrosive medium is extremely small on account of plenty of air pockets trapping underneath the laser-induced micro-nano structures [11,12] .…”

One-Step Methods to Fabricate Durable Superhydrophobic Coatings for Flexible Electronic Sensors

“…To date, a few studies on flexible conductive superhydrophobic surfaces have been reported [26][27][28]. As is known, superhydrophobic surfaces depend on two main factors: surface roughness and low surface energy [29,30]. The surface roughness is mainly provided by various surface treatment methods, and low surface energy can be obtained from fluorinated or long chain polymers [31].…”
