Summary: Poly(ethyl ethylene phosphonate)-based methacrylic copolymers containing polysiloxane methacrylate (SiMA) co-units were proposed as surface-active additives for novel PDMS-based coatings for marine antifouling applications. The hydrolysis of these polymers in marine-like conditions and their potential as erodible films were studied. All films underwent surface reconstruction upon immersion in water, becoming more hydrophilic, with different hydrophilic units affecting the extent of surface modification. Films with 10 wt% of the PEtEP-based copolymer showed maximized Ficopomatus enigmaticus release and performed better in bioassays than those with 20 wt% loading, independent of copolymer nature.

Summary: In this study, two types of amphiphilic random terpolymers were synthesized and evaluated against diverse marine fouling organisms to study their antifouling and fouling-release properties. The precursor amine terpolymers were synthesized by atom transfer radical polymerization with different comonomer ratios and initiators, followed by selective oxidation to introduce nitroxide radical functionalities. The terpolymers were then incorporated into a PDMS host matrix to create coatings. The effectiveness of these systems against different fouling organisms was observed, with the nonfluorinated PEG and nitroxide combination identified as the most effective formulation against B. improvisus and F. enigmaticus.

Summary: A novel surface-active copolymer based on PVP and PDMS was designed and incorporated into a PDMS matrix to form a surface-renewable antifouling coating. The copolymer exhibited outstanding antifouling and fouling-release properties, with higher PVP content leading to better performance. The long-term antifouling capability of the coating was demonstrated in marine field tests, offering a promising solution to marine biofouling issues.

Summary: A novel low surface energy coating was prepared by compounding natural polymerized tung oil (PTO) and urushiol-based benzoxazine copper polymers (UBCP). The addition of PTO toughened the UBCP and reduced the modulus of the composite coatings, weakening the adhesion of fouling organisms. Moreover, a small concentration of copper ions released from the composite coatings showed synergistic antifouling effects.

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: Poloxamers, also known as Pluronics, have been found to alleviate cellular membrane damage, but the underlying protection mechanism is still unclear. This study investigated the impact of poloxamer molar mass, hydrophobicity, and concentration on the mechanical properties of lipid vesicles, revealing that poloxamers tend to decrease the stretching modulus. The study provides important insights into how poloxamers interact with lipid membranes and protect cells from various stresses.

Summary: A series of model poly((+/-)-lactide) graft copolymers were synthesized and used to study the transition from star-like to bottlebrush structure in shear and extensional flows. Small-amplitude oscillatory shear and extensional rheometry measurements were conducted on samples with different backbone degrees of polymerization. The transition from star-like to bottlebrush structure occurred at a backbone degree of polymerization between 50 and 69. In extensional flows, the star-like melts exhibited no melt strain hardening, while the bottlebrush melts showed prominent strain hardening. These findings are important for designing bottlebrush materials with strain hardening properties for various processing methods involving extensional flows.

Summary: The performance of sustainable polymers can be modified and enhanced by incorporating functional groups in the backbone of the polymer chain that increases intermolecular interactions, thus impacting the thermal properties of the material. This study investigates the role of intermolecular interactions on the crystallization of these polymers and proposes a systematic strategy to modify the thermal properties and crystallization kinetics by incorporating functional groups. The results show that the thermal transitions and crystallization kinetics of PEs can be independently tuned by varying their chemical structure.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
