Investigating the anti-bioadhesion properties of short, medium chain length, and amphiphilic polyhydroxyalkanoate films.
Silicone materials are widely used in fouling release coatings, but developing eco-friendly protection via biosourced coatings, such as polyhydroxyalcanoates (PHA) presents a major challenge. Anti-bioadhesion properties of medium chain length PHA and short chain length PHA films are studied and compared with a reference Polydimethylsiloxane coating. The results highlight the best capability of the soft and low-roughness PHA-mcl films to resist bacteria or diatoms adsorption as compared to neat PDMS and PHBHV coatings. These parameters are insufficient to explain all the results and other properties related to PHA crystallinity are discussed. Moreover, the addition of a low amount of PEG copolymers within the coatings, to create amphiphilic coatings, boosts their anti-adhesive properties. This work reveals the importance of the physical or chemical ambiguity of surfaces in their anti-adhesive effectiveness and highlights the potential of PHA-mcl film to resist the primary adhesion of microorganisms.
期刊介绍：
Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion.
Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context.
Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
