Antifouling properties of amphiphilic poly(3-hydroxyalkanoate): an environmentally-friendly coating

Impact of Molecular Weight on Anti-Bioadhesion Efficiency of PDMS-Based Coatings

“…For example, PDMS-0.8K has an elastic modulus nine times higher than that of PDMS-10K. However, these values were in good accordance with previous studies, as elastic moduli for fouling release coatings are typically ranged between 0.2 and 9 MPa [3,[23][24][25]. In their recent study, similar results were observed by Sun et al [26].…”

“…ing to the literature [22,23]. The RMS values of the films were between 1 and 6 nm, with a slight increase of the RMS when increasing molecular weight of the PDMS, indicating the molecular weight could impact the surface roughness of coatings.…”

“…All PDMS coatings exhibit a typical mesh-like network structure as described by Drebezghova et al [22]. The low roughness of the coatings was not surprising according to the literature [22,23]. The RMS values of the films were between 1 and 6 nm, with a slight increase of the RMS when increasing molecular weight of the PDMS, indicating the molecular weight could impact the surface roughness of coatings.…”

Biobased Anti-Adhesive Marine Coatings from Polyhydroxyalkanoates and Polysaccharides

“…Finally, PHAs have recently been investigated as a source of new chiral compounds (synthons) which can be used as precursors in the pharmaceutical and chemical industries, since enantiopure (R)-3-hydroxyalkanoic acids are difficult to obtain by conventional chemical processes [61]. However, studies on the use of PHAs for the preparation of nonadhesive marine coatings are sparse and only one recent study has evaluated the potential of these biopolymers as a matrix for fouling release coatings [62]. Nevertheless, PHAs have been used to evaluate the factors controlling bacterial attachment and/or biofilm formation in polymeric surfaces [63][64][65][66].…”

Synthesis of fully bio-based poly (3-hydroxybutyrate)-oligo-2-ethyl oxazoline conjugates

“…PHB modification reactions are important to prepare new PHB derivatives for some industrial and medical applications ( Hazer, 2010 ; Hazer et al, 2012 ; Guennec et al, 2021 ). Some of them are halide derivatives ( Arkin and Hazer, 2002 ; Yalcin et al, 2006 ; Erol et al, 2020 ), chitosan derivatives ( Arslan et al, 2007 ), diethanol amine derivatives ( Tuzen et al, 2016 ), trithiocarbonate derivatives ( Hazer et al, 2020 ), methyl salicylate derivatives ( Hazer et al, 2021 ), ricinoleic acid derivatives ( Ullah et al, 2024 ), PEG derivatives ( Hazer et al, 1999 ; Wadhwa et al, 2014 ), and caffeic acid derivatives ( Abdelmalek et al, 2023 ).…”
