“…The adhesion of the coating depends on the thickness of the coating and the roughness of the coating surface, among other factors. This has been mentioned in our previous studies [26]. The lowest adhesion strength of PRE-0 coating to glass and steel plates was 1.9 ± 0.05 Gel permeation chromatography (GPC) analysis revealed the molecular weight (Mw = 13.4-18.8 kDa) and narrow polydispersity (PDI = 1.76-2.21) of the PRE polymers, as well as their high yields (84-89%) (Figure 2F).…”

Capsaicin has been extensively studied for its excellent antifouling activity and very low environmental toxicity. However, mixing natural capsaicin with coatings can cause rapid capsaicin leakage, severely shortening its antifouling cycle. In this study, we describe the preparation and performance of a new capsaicin-modified marine antifouling organofluorosilicone, which is based on silicone and fluorine acrylate monomers covalently bound to an organic antimicrobial monomer, HMBA (N-(4-hydroxy-3-methoxybenzyl)-acrylamide) on a polymer network. The chemical grafting of HMBA into the polymer has improved the problem of short antifouling life of the coating due to antifouling agent leakage and the environmental pollution caused by the leakage. The study focused on the synthesis of pristine acrylate monomers with organic bioactive groups prepared from vanillin amine salts and their co-polymerization in the presence of distal acrylate oligomers. The resulting cross-linked films were characterized using infrared spectroscopy, contact angle, and adhesion analyses. The results indicate that the materials had good adhesion, low surface energy, and were resistant to prolonged immersion in water. The polyacrylate coating synthesized from acrylate exhibited antibacterial and anti-algae activity. Biological tests on the marine microorganisms, Pseudomonas species, Shewanella species, and Navicula incerta, revealed a 97%, 98%, and 99% reduction compared to the blank control group, respectively, indicating that the coating has strong anti-adhesive ability. This work is expected to develop a promising material for marine antifouling.

“…In comparison to PIAT, PIHT had a lower toughness (3.65 MJ m –3 ) and elongation at break (247%), which could be attributed to a decrease in the number of H-bond donors and acceptors. Furthermore, as shown in Figure d, PTAT exhibits superior mechanical properties when compared with the majority of previously reported self-healing materials. − ,− In addition, at tensile rates of 100 and 300 mm min –1 , PTAT still has excellent mechanical properties compared to those of the other three elastomers (Figure S7 and Table S4).…”

High-performance elastomers that possess a combination of high mechanical toughness and fast healability have garnered extensive interest because of their diverse application potential. Inspired by the unique multiple hydrogen bond (Hbond) structure of spider silk and the rapid dynamic exchange of hindered urea bonds (HUBs), a self-healing polyurea elastomer with ultrahigh toughness was designed by incorporating dynamic sextuple H-bonds and HUBs into the polymer chain. Such a design affords high stretchability (1586%), excellent toughness (45.53 MJ m −3 ), good self-healing efficiency (91.6%), fracture energy (39.68 kJ m −2 ), and recyclability. The high mechanical performance and good healability are attributed to the presence of reversibly crosslinked noncovalent sextuple H-bonds and dynamically covalent HUBs, which have been validated by stress relaxation tests. Meanwhile, by substituting the chain extender adipic dihydrazide with hexamethylenediamine, which possesses a comparable structure but fewer amide bonds, the effect of sextuple H-bonds on elastomers was confirmed. More importantly, when a conductive layer of graphene oxide was applied to the surface of the resulting elastomer, the elastomers exhibited potential applications in strain sensors.

“…Therefore, the development of catalyst-free, self-healing core materials can expand the range of applications for self-healing materials and avoid the effects of catalyst failure. One-component self-healing systems without the aid of catalysts and curing agents, represented by dry oils, 29–31 isocyanates, 32–34 and active silicones, 35–37 have been rapidly developed. The molecular structure of the repair agent of this system usually contains active functional groups that can polymerize under the action of O 2 , H 2 O, or light to realize the repair of coating defects and show good self-repair and corrosion resistance.…”
