Abstract
Self-healing superhydrophobic coatings have attracted extensive attention in recent years because of their excellent properties of water-resisting, anti-fouling, and self-healing. However, it faces many challenges such as decontamination efficiency, environmental adaptability, and cost. Herein, design and preparation of tri‑boronic acid compounds containing imine bonds (MP), and 7 kinds of MP hydrogels were obtained at a wide pH range (pH = 1, 3, 5, 7, 9, 11, and 13). The structure and morphology of MP hydrogels were characterized by FTIR and SEM. WCA tests demonstrate the hydrophobicity of the MP compound and MP xerogel. The rheological results demonstrate that the hydrogel with pH 5 exhibits the greatest energy storage modulus (G') and displays the strongest resistance to external force. MP incorporated into PDMS-SiO2 coating to fabricate PDMS-SiO2-MP coating by spraying method. Compared to PDMS-SiO2 coating, PDMS-SiO2-MP coating not only enhanced the hydrophobicity, adhesion, friction resistance, and anti-corrosion but also provided self-healing properties. Moreover, when PDMS-SiO2-MP coating was sprayed on the surface of glass, aluminum, plastic, wood, paper, and sponge, it indicated a superhydrophobic effect. The filter paper was coated by PDMS-SiO2-MP has good oil-water separation abilities, and its oil-water separation efficiency remains above 90 % after 10 cycles.
期刊介绍:
The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as:
• Chemical, physical and technological properties of organic coatings and related materials
• Problems and methods of preparation, manufacture and application of these materials
• Performance, testing and analysis.
