Summary: This study presents a novel approach to combat marine biofouling by developing a polymeric coating with integrated fouling killing, resistance, and releasing functions. The coating degrades at the surface/seawater interface, generating antifouling and zwitterionic groups for effective protection. The controllable degradation rate and synergistic antibacterial effects make this coating a promising solution to the challenge of marine biofouling.

Summary: A new self-healable coating formulation based on waterborne organic silicone polyurethane has been proposed, which integrates disulfide groups into polyurethane molecules. The coating demonstrates high self-healing efficiency of up to 90.8% and maintains excellent superhydrophobic performance on cotton fabric even after severe damage. It also exhibits outstanding self-healing ability, as the damaged surface can self-heal after heating. Moreover, the coating shows great durability, retaining superhydrophobicity and oil/water-separation efficiency even after multiple washes and wearings.

Summary: This study investigates the effects of the soft block fraction and H-bond state in thermoplastic polyurethanes on autonomous entropy-driven scratch closure and barrier restoration. It is found that while softer polyurethanes can efficiently close cracks, they are unable to sufficiently restore barrier properties.

Summary: Marine biological pollution is a global challenge in marine engineering. MXene nanosheets and zwitterionic polymers have been investigated as effective materials for marine anti-biofouling. In this study, MXene-PDA was prepared by self-assembling polydopamine layer on the MXene nanosheets, followed by introducing the zwitterionic polymer PEIS through a Michael addition reaction to obtain MXene-PEIS. The resulting MXene-PEIS exhibited excellent antifouling performance through the cooperative antifouling effect of MXene nanosheets and PEIS (88% improved antibacterial rate and 98% decrease in microalgae adhesion density). Furthermore, the nanocomposite antifouling coatings (MXene-PEIS/SP) showed good antifouling performance due to the synergy among MXene, PEIS, and self-polishing coatings.

Summary: In this study, poly(ethylene glycol) (PEG) was successfully grafted onto polyurethane (PU) surfaces using a simple and efficient transurethanization reaction. The surface modification resulted in the formation of antiadhesive hydrophilic surfaces, which showed lower protein adsorption, cell, platelet, and bacterial adhesion compared to untreated surfaces. This study demonstrates the potential of the modified surfaces for biomedical applications.

Summary: Surface fouling is a common problem that leads to economic loss and health risks in all materials and devices. Inspired by the antifouling nature of cell membrane, zwitterionic coating antifouling strategy has been developed as a strong technique. The use of self-adhesive polydopamine (PDA) enables the construction of cell membrane mimetic antifouling coatings on all materials and devices. This review summarizes the design concepts, construction techniques, and recent progress of antifouling zwitterionic polymer coating applications, with emphasis on coating stability and crosslinking enhancement for practical use.

Summary: This study achieved hydrophilization of thermoplastic polyurethane (TPU) surface through the inverted grafting-to approach, using amphiphilic block copolymers. The hydrophilic surfaces displayed significantly reduced water contact angles and a drastic decrease in coefficient of friction, suggesting potential application as lubricious coating for TPU-based urinary catheter tubes.

Summary: In this study, a series of modified silicone coatings were prepared by introducing PDMS2200 into the soft segment of polyurethane. The structure, morphology, roughness, surface energy, tensile properties, and antifouling properties of the modified coatings were investigated. It was found that PDMS2200 could increase the surface-free energy and reduce the elastic modulus of the coatings, but excessive microphase separation would decrease the tensile properties. The PED-TDI polyurethane-modified silicone coating prepared with the formula of PU-Si17 showed the best tensile properties and antifouling properties.
