“…Hydrolyzable polymers have already been used in the field of antifouling coatings, for the development of biocides-based erodible coatings. Bressy’s group synthesized poly(trialkylsilyl methacrylate)s to develop coatings with tunable erosion profiles [ 36 , 37 , 38 ], Zhang’s and Réhel’s groups worked on degradable polyesters for antifouling applications [ 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. Copolymers based on poly(ε-caprolactone), poly(δ-valerolactone), polybutylene succinate, poly(L-lactide), poly(ethylene adipate), and poly(2-methylene-1,3-dioxepane) were synthesized to promote the erosion of the polymer matrix and the controlled release of biocides.…”

Hydrolyzable Additive-Based Silicone Elastomers: A New Approach for Antifouling Coatings

Fouling Release Coatings are marine antifouling coatings based on silicone elastomers. Contrary to commonly used biocide-based antifouling coatings, they do not release biocides into the marine environment, however, they suffer from poor antifouling efficacy during idle periods. To improve their antifouling performances in static conditions, various amounts of hydrolyzable polymers were incorporated within a silicone matrix. These hydrolyzable polymers were chosen for the well-known hydrolytic degradation mechanism of their main chain, e.g. poly(ε-caprolactone) (PCL), or of their ester pending groups, e.g. poly(bis(trimethylsilyloxy)methylsilyl methacrylate) (PMATM2). The degradation kinetics of such hydrolyzable silicone coatings were assessed by mass loss measurements during immersion in deionized water. Coatings containing PMATM2 exhibited a maximum mass loss after 12 weeks, whereas PCL-based coatings showed no significant mass loss after 24 weeks. Dynamic contact angle measurements revealed the modifications of the coatings surface chemistry with an amphiphilic behavior after water exposure. The attachment of macrofoulers on these coatings were evaluated by field tests in the Mediterranean Sea, demonstrating the short or long-term antifouling effect of these hydrolyzable polymers embedded in the silicone matrix. The settlement of A. amphitrite barnacles on the different coatings indicated inhospitable behaviors towards larval barnacles for coatings with at least 15 wt % of additives.

“…In the past several decades, PUs have found various applications. These range [ 1 , 2 ] from foams, elastomers, adhesives, paints and fibres (spandex) and so on to special coatings [ 3 – 5 ]. For each application, the PU compositions selected afford needed physical characteristics that may be uniquely required in the particular application.…”

Synthesis and structure/properties characterizations of four polyurethane model hard segments

Four model polyurethane (PU) hard segments were synthesized by reaction of butanol with four typical diisocyanates. The four diisocyanates were aromatic 4,4′-diphenylmethane diisocyanate (4,4′-MDI) and MDI-50 (50% mixture of 2,4′-MDI and 4,4′-MDI), cycloaliphatic 4,4′-dicyclohexylmethane diisocyanate (HMDI) and linear aliphatic 1,6-hexamethylene diisocyanate (HDI). FTIR, 1H NMR, 13C NMR, MS, X-ray and DSC methods were employed to determine their structures and to analyse their crystallization behaviours and hydrogen bonding interactions. Each of the four PU compounds prepared in the present work displays unique spectral characteristics. The FTIR bands and NMR resonance peaks assigned in the four samples thus provide a reliable database and starting point for investigating the relationship between hard segment structure and the crystallization and hydrogen bonding behaviour in more complex-segmented PU compositions.

“…5,6 Among them, 2-methylene-1,3-dioxepane (MDO), 5,6-benzo-2-methylene-1,3-dioxepane (BMDO) or 2-methylene-4-phenyl-1,3-dioxolane (MPDL) are by far the most used ones. 7,8 For example, copolymerization of common vinyl monomers with CKAs by conventional free-radical polymerization or RDRP has received tremendous attention 8 to design degradable materials for applications in drug delivery, [9][10][11] marine antibiofouling technologies, [12][13][14] gene/DNA transfection, 15 tissue engineering 16 and others. 17,18 Yet, despite promising proofs of concepts, important limitations still stand, such as the poor hydrolytic degradation of CKA-containing copolymers in physiological conditions, which still cannot compete with the most popular polyesters like poly(lactic-co-glycolic acid) (PLGA) or even poly(lactic acid) (PLA).…”

Vinyl polymers are the focus of intensive research due to their ease of synthesis and the possibility of making well-defined, functional materials. However, their non-degradability leads to environmental problems and limits their use in biomedical applications, allowing aliphatic polyesters to still be considered as the gold standards. Radical ring-opening polymerization (rROP) of cyclic ketene acetals (CKAs) is considered the most promising approach to impart degradability to vinyl polymers. Despite considerable efforts, rROP-synthesized materials still exhibit poor hydrolytic degradation and thus cannot yet compete with traditional polyesters. Here we show that a simple copolymerization system based on acrylamide and CKA can lead to well-defined copolymers with faster hydrolytic degradation than that of polylactide and poly(lactide-co-glycolide). Moreover, by changing the nature of the CKA, the copolymers were either watersoluble or exhibited tunable upper critical solution temperatures (UCST) relevant for mild hyperthermiatriggered drug release. To illustrate the interest of these new copolymers, we showed that they were cytocompatible on different healthy cell lines and we synthesized amphiphilic diblock copolymers that were formulated into degradable, UCST nanoparticles by an all-water nanoprecipitation process. Given all its important benefits, we anticipate this copolymerization system to offer new avenues in different applications such as biodegradation of commodity polymers, drug delivery or tissue engineering.
