Published: April 3, 2022

Abstract Slippery liquid‐infused porous surface (SLIPS) has received widespread attention in the antifouling field, while its controllability of lubricity and durability lubricant are relatively insufficient. In this study, inspired by hagfish's defensive behavior secreting mucus to escape from predators, a smart SLIPS marine coating is prepared, which possesses responsively switching lubrication modes self‐healing property. The responsive supramolecular interaction between azobenzene (Azo) α‐cyclodextrin (α‐CD) introduced regulate SLIPS. cis ‐Azo converted trans combined with α‐CD under visible light or heating, driving shrinkage polymer chains squeeze stored surface. self‐replenishment can adjust switch “enhancive” “normal” smartly, adapts different occasions. Moreover, disulfide hydrogen bonds enhance performance (91.73%). summary, it efficient self‐cleaning, anti‐protein, antibacterial, anti‐algae properties, 180‐day real field during boom season (the longest period test reported materials), demonstrates promising application neritic sea equipment other fields.

Smart Self-Puffing Phosphite-Protonated Siloxane Network Enables Multifunctional Transparent Protection

ACS Materials Letters, Journal Year: 2023, Volume and Issue: 5(9), P. 2398 - 2407

Published: Aug. 4, 2023

Harsh-condition protective materials are essential for resisting various types of environmental damage, such as fire, microbes, scratches, and etc. However, integrating multiple functions in one transparent flexible material without sacrificing each other remains a formidable challenge. Here, we demonstrate smart-puffing phosphite-protonated siloxane (PSiP) that simultaneously exhibits excellent fire protection, high-temperature insulation, antibacterial, antimold, self-healing properties. A facile one-step method is developed to create this microporous PSiP using (3-aminopropyl)triethoxysilane phosphite via hydrophilic–hydrophobic interaction-driven self-assembly. Notably, employs an intelligent thermal-responsive self-puffing behavior achieve effectively blocking 87.8% 1400 °C heat. The unique dynamic network with high transparency (>92% the visible region) affords ability well potent defense against bacteria (>99% efficiency). Our findings open up new avenue developing transparent, flexible, high-performance multihazard potential applications buildings, windshields, electronics, beyond.

A Universal Strategy for Constructing Robust and Antifouling Cellulose Nanocrystal Coating

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 32(8)

Published: Nov. 9, 2021

Abstract Super‐hydrophilic cellulose nanocrystals (CNCs) hold great potential in fabricating antifouling surfaces based on their high‐water binding affinity. However, integrating CNCs as a robust surface coating substrate still remains challenge due to its limited adhesion property. Herein, inspired by marine bio‐adhesive strategy, facile yet universal method is developed for tightly anchoring various substrates with an intermediate adhesive layer composed of tannic acid (TA)/polyethylenimine (PEI)/vanadium(V). Introducing V 3+ ions the assembly process significantly reduces roughness TA/PEI/V bio‐glue via coordination chemistry, thus achieving highly‐dense structure and outstandingly low root‐mean‐square (≈2 nm). The super‐hydrophilic exhibits outstanding properties inhibiting oil adhesion, protein adsorption or cell attachment, maintaining structural integrity wettability over 100 friction cycles. Additionally, CNCs‐coated polyvinylidene fluoride (PVDF) membrane shows ultra‐high water flux 6000 L m –2 h –1 bar achieves nearly 100% permeating recovery ratio separation toluene‐in‐water emulsion containing foulants. This study demonstrates settle long‐standing integration rigid materials broad engineering environmental applications.

A coating with programmable multifunctionality based on application requirements is desirable. However, it still a challenge to prepare hard and flexible quick self-healing ability. Here, but reversible Si–O–Si network enabled by aminopropyl-functionalized poly(silsesquioxane) triethylamine (TEA) was developed. On the basis of this network, basic coatings excellent transparency, hardness, flexibility, properties can be prepared filling soft polymeric micelles into networks. The highly cross-linked continuous endows hardness (H = 0.83 GPa) higher than those most polymers < 0.3 GPa), while uniformly dispersed decrease Young's modulus (E 5.89 value as low that common plastics, resulting in an H/E 14.1% elastic recovery rate (We) 86.3%.
