The freezing phenomenon poses significant challenges in many fields, causing serious casualties and economic losses. Compared with traditional measures, active/passive coupled anti-deicing technology exhibits greater adaptability effectiveness diverse scenarios. Herein, an electrothermal/superhydrophobic coating featuring a sandwich structure was proposed for applications. Benefiting from the hydrophobic modified micro-nanostructure, this superhydrophobic boasted remarkable abilities to delay icing repel water adhesion, rendering it ideal combating rain. Under certain electrothermal power density, could be heated quickly evenly. Furthermore, has proven highly capable of enduring prolonged continuous heating rigorous high–low-temperature cycling tests, delivering exceptional performance. To evaluate its dynamic anti-icing performance, wind tunnel tests were conducted, which demonstrated that can prevent properties, even under harsh environments. This work would inspire design promote practical engineering

The crosslinking and decrosslinking of fluorinated diblock copolymer from RAFT emulsion polymerization toward surface anti‐icing

Journal of Polymer Science, Journal Year: 2024, Volume and Issue: 62(18), P. 4186 - 4200

Published: June 15, 2024

Abstract Here, we demonstrate disulfide‐crosslinked polyfluoroacrylate AB block copolymer films with excellent anti‐icing properties. The fluorinated latexes of copolymers were synthesized via two‐step reversible addition‐fragmentation chain‐transfer (RAFT) emulsion polymerization using polyacrylic acid and its sodium salts as the hydrophilic A‐block, polyhexafluorobutyl acrylate hydrophobic B‐block. Diacetone acrylamide was copolymerized in different blocks a crosslinking anchor. A disulfide‐containing compound dithiodipropionic dihydrazide chosen agent to form enhance mechanical properties, surface swelling properties films. It has proved that site great impact on film formation process which turn affects performance. B‐block crosslinked showed better resistance water while A‐block more organic solution resistant. also possessed due high F/O value. Furthermore, decrosslinking experiments conducted reductant tris(2‐carboxyethyl)phosphine hydrochloride break disulfide bond. recycling rate could reach >90% reached >75%.

Heterogeneous micro-architectonic integration of SU-8 and highly entangled polyacrylamide hydrogel to realize cut-resistant soft superhydrophobic surfaces

Journal of Micromechanics and Microengineering, Journal Year: 2024, Volume and Issue: 34(10), P. 105007 - 105007

Published: Sept. 3, 2024

Abstract This paper presents a novel idea to create cut-resistant superhydrophobic (SHPo) surfaces by integrating an array of SU-8 micropillars on highly entangled polyacrylamide (PAAm) hydrogel substrate. We begin demonstrating that this PAAm exhibits superior resistance cutting while being as transparent, flexible, and stretchable other polymeric substrates like polydimethylsiloxane (PDMS). Currently, there are no well-known methods or chemicals directly integrate with covalent bond. To overcome challenge, we introduce thin layer chemically modified PDMS between the so bonds can be formed both SU-8/PDMS interface PDMS/PAAm interface. After validating reliability bonding in our experiments, develop heterogeneous integration process fabricate desired SHPo surface. demonstrate critical role achieving surface, contrast new surface reference version uses substrate instead. conduct microscopic inspections using scanning electron microscopy contact angle goniometer before after two surfaces. These evaluations show significant differences their structural integrity behavior water interaction.
