“…27−29 However, PEG is susceptible to oxidation in complex media, thus its long-term application has been limited. 26 Pranantyo et al 28 reported that the hyperbranched polyglycerol had higher stability against oxidation as antifouling coatings but its globular structure is too bulky and hence not suitable to be used as a cross-linker. Dehghani et al 29 precisely tuned the polymer brush architectures by introducing cross-linkers with different concentrations and lengths, including tetra(ethylene glycol) dimethacrylate (TEGDMA) and di(ethylene glycol) dimethacrylate (DEGDMA), to modulate the film's physicochemical properties and antifouling abilities.…”

To improve antifouling and anticorrosion properties of stainless steel (SS), well-controlled polycationic brushes were robustly anchored on the steel substrates by biomimetic polydopamine layers. Self-polymerization of dopamine on the steel surface was first carried out to introduce an alkyl bromine atom transfer radical polymerization (ATRP) initiator. Subsequent grafting of the crosslinked poly(2-(dimethyamino)ethyl methacrylate (PDMAE-MA) layer from the bromine-terminated steel substrates was accomplished by surface-initiated ATRP of DMAEMA with poly(ethylene glycol) dimethacrylate (PEGDMA) as a crosslinker, followed by N-alkylated reaction of the PDMAEMA chains to introduce a high surface density of positively charged quaternary ammonium salts. The as-synthesized SS substrates tethered with cross-linked polycationic brushes demonstrated enhanced antifouling against the Amphora coffeaeformis attachment and barnacle cyprids settlement and exhibited good antibacterial and anticorrosion effects against the marine bacteria Pseudomonas sp. The functionalized SS substrates with good antifouling and anticorrosion capabilities are potentially useful in marine environments.

“…Making use of natural barnacle cement as biomimetic surface anchors for surface modification has many advantages, including good stability, substrate-independent adhesion, rich functional groups, biocompatibility, and environmental friendliness ( Pranantyo et al, 2017 ). However, it is quite challenging to collect a large quantity of liquid barnacle cement for large-scale applications, primarily because barnacle cement has low production and can be easily contaminated during sampling.…”

Wet adhesion technology has potential applications in various fields, especially in the biomedical field, yet it has not been completely mastered by humans. Many aquatic organisms (e.g., mussels, sandcastle worms, and barnacles) have evolved into wet adhesion specialists with excellent underwater adhesion abilities, and mimicking their adhesion principles to engineer artificial adhesive materials offers an important avenue to address the wet adhesion issue. The crustacean barnacle secretes a proteinaceous adhesive called barnacle cement, with which they firmly attach their bodies to almost any substrate underwater. Owing to the unique chemical composition, structural property, and adhesion mechanism, barnacle cement has attracted widespread research interest as a novel model for designing biomimetic adhesive materials, with significant progress being made. To further boost the development of barnacle cement–inspired adhesive materials (BCIAMs), it is necessary to systematically summarize their design strategies and research advances. However, no relevant reviews have been published yet. In this context, we presented a systematic review for the first time. First, we introduced the underwater adhesion principles of natural barnacle cement, which lay the basis for the design of BCIAMs. Subsequently, we classified the BCIAMs into three major categories according to the different design strategies and summarized their research advances in great detail. Finally, we discussed the research challenge and future trends of this field. We believe that this review can not only improve our understanding of the molecular mechanism of barnacle underwater adhesion but also accelerate the development of barnacle-inspired wet adhesion technology.

“…However, TA can also be used as a chemical cross-linker. Various researchers have performed different chemical cross-linking reactions such as phenol-amine Michael/Schiff base reaction, 40,41 phenol−thiol Michael addition, 42 phenol−epoxy ring-opening reaction, 43,44 phenol-alcohol Mitsunobu reaction, 45 phenol−aldehyde reaction, 46 and phenolic acylation. 47 In this study, we developed a green, low-cost, and scalable process to coat inert fibers such as PP with a network of chitosan cross-linked with TA under mild conditions (water, pH = 8.5, O 2 bubbling, 60 °C).…”

A green cross-linking and straightforward method to physically trap inert fibers in a network of chitosan was implemented. The cross-linking reaction involved a biosourced and biocompatible cross-linker [tannic acid (TA)] and mild conditions in water (pH = 8.5, O 2 bubbling, 60 °C, 3 h). The steric hindrance of TA led to a low but effective cross-linking rate leaving parts of primary amines of chitosan available for postmodification such as the grafting of quaternary ammoniums for antibacterial purposes. Fabric's coatings were characterized by scanning electron microscopy coupled with energy-dispersive X-ray, infrared spectroscopy, and weight gain measurements. This allowed the optimization of process conditions. No significant antioxidant activity was observed on fabrics coated with chitosan cross-linked with TA, confirming the low cross-linking rate. This low cross-linking rate allowed grafting of quaternary ammoniums for antibacterial purposes, but it is possible to consider grafting other active molecules. Biological assays were conducted on this coating to assess its antibacterial properties. Reduction of bacterial colonization on both Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative), two of the major strains responsible for nosocomial infections, confirmed the potential of the coating for antibacterial purposes. This study displays a simple and ecofriendly process to coat inert fabrics with a chitosan network containing reactive functions (primary amines) available for grafting active molecules for various purposes.
