Motivated by the need for materials that balance durability with environmental sustainability, we assessed the feasibility of polyhydroxyalkanoate (PHA) coatings as a strategy to prolong the service life of burlap fabric. Three PHA-based polymers were applied by dip-coating, single-sided melt pressing, and double-sided melt pressing and then immersed in seawater at ∼5 m depth for 288 days. Visual observations, evaluation of the end-point mass loss data, and complementary molecular weight and X-ray scattering analyses show that durability depends on the processing method and polymer crystallinity: double-sided melt-pressed samples retained the most mass (compared to single-sided, dip-coated, and uncoated), and mass loss decreased with increasing initial PHA polymer crystallinity. Additionally, these data support a degradation pathway in which amorphous domains are preferentially eroded and crystalline lamellae thicken due to relaxation of entanglement constraints. These processing-crystallinity-durability relationships suggest that the residence time may be tuned to match restoration schedules, positioning melt-pressed PHA coatings as an ecologically sustainable alternative to persistent plastic materials.</p>","PeriodicalId":55639,"journal":{"name":"ACS Applied Engineering Materials","volume":"4 4","pages":"1795-1801"},"PeriodicalIF":3.5,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13126563/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147823890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Theoretical derivations showed that collapse can occur due to plastic or elastic failure, where, in the case of plastic failure, the collapse pressure should equal that of the burst pressure. Combining experimental results with our model revealed that for our membranes, plastic failure was the dominant failure mechanism. The model was able to accurately predict the influence of the membrane's porosity on the collapse pressure. However, the model seemed to only partially predict the influence of different geometric dimensions of the HF on its collapse pressure. Interestingly, though, the results showed that, for 7 out of 8 HF membranes, the burst pressure was indeed similar to the collapse pressure, highlighting that the burst pressure can be used as an indicator for the collapse pressure of the outer-skinned HF membranes.

Here, we solved the problem by producing three-layer laminate films that are fully biobased and biodegradable. Two different MP films (originating from a mixed microbial culture and <i>Delftia tsuruhatensis</i> biomass) were sandwiched between two different moisture-shielding polyhydroxyalkanoate (PHA) films (a poly-(3-hydroxybutyrate-<i>co</i>-3-hydroxyvalerate) and a poly-(3-hydroxybutyrate-<i>co</i>-3-hydroxyhexanoate) material). The low-temperature melting features of the PHAs made them suitable for lamination through hot-pressing with the MPs. Liquid-water-resistant and UV-blocking laminates could be obtained, where the individual layers were also possible to delaminate as a possible recycling solution, where the MP layer could potentially be used as a fertilizer and the PHA mechanically recycled into similar or other products or composted. The laminates showed, in the best cases, an oxygen permeability of 2 cm³ mm/(m² day atm) and a water vapor permeability below 0.1 g mm/(m² day).

Recently, a nanohydrogel coating was demonstrated to have excellent antiadhesive properties toward drinking water microorganisms, making it a promising approach to alleviate biofilm formation in DWDS systems. However, the used coating procedure was not suitable for large surface areas and the stability of the coating under various physicochemical conditions was not assessed. This study proposes an optimized coating procedure for poly-(vinyl chloride) (PVC)-based drinking water piping and evaluates the stability of this poly-(<i>N</i>-isopropylmethacrylamide) (PNIPAM) based nanohydrogel coating and its ability to prevent microbial adhesion under drinking water conditions. Stability was assessed through detailed scanning electron microscopy, atomic force microscopy, and contact angle measurements after accelerated stress tests under different physicochemical conditions, including temperature, pH, salt concentration, and surfactant concentration. Microbial adhesion was tested in 35 day long recirculation experiments performed in a lab-scale DWDS under relevant drinking water conditions. The coating exhibited a very high stability under harsh pH conditions (1.5-13.5), high and low temperatures (4-70 °C) and extreme salt concentrations (0.1-6000 mM). However, at high surfactant concentrations, above the critical micellar concentration, some instability was observed. Against DWDS conditions, the coating remained stable over 35 days, showing a significant reduction (>80%) in adhesion of microorganisms. Overall, these findings support the use of the PNIPAM nanohydrogel coating as a scalable and stable solution to microbial adhesion in drinking water environments, offering a promising alternative or support to disinfection treatments to reduce biofilm formation in DWDS systems but with high potential toward other applications due to the highly stable nature of the nanohydrogel coating.</p>","PeriodicalId":55639,"journal":{"name":"ACS Applied Engineering Materials","volume":"4 2","pages":"650-660"},"PeriodicalIF":3.5,"publicationDate":"2026-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12955759/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147357565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
