Environmentally Friendly Antifouling Coatings Based

2017/6/7Marine biofouling causes huge economic losses and serious problems to maritime industries. Consequently, there is a great demand for environmentally friendly antibiofouling technology. In the present study, we developed novel antifouling coatings by incorporating butenolide derived from marine bacteria into biodegradable poly(ε-caprolactone) based polyurethane. Measurements of mass loss

Effective anti-fouling strategies currently primarily rely on toxic additives in coatings (biocide-containing coatings). Their negative impact on the environment and the resulting ever stricter legislation means that biocide-free coatings are likely to become increasingly important in the future.

Inorganic precursor peroxides for antifouling coatings.

2009/6/1Anti-fouling efficiency was established based on a laboratory assay including barnacle larvae and panels immersed in seawater. Experimental methods and materials Both calcium- and magnesium-peroxides were obtained from Solvay as Ixpcr 75C[R], and Ixper 35 M[R], respectively, and strontium- and zinc-peroxides were purchased from Sigma Aldrich.

Anti-fouling paint - a category of commercially available underwater hull paints (also known as bottom paints) - is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth and/or facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability (see also biofouling).

Abstract Polyimide-copper layers consisting of individual capsule-like splats were one-step fabricated by solution precursor flame spray through controlling the reaction between dianhydride and diamine dissolved in copper nanoparticles-containing dimethylformamide solvent. The polyimide splat exhibited hollow structure with an inner pore of 10–15 μm and a tiny hole of 1–5 μm on its top

Highly Efficient Antimicrobial and Antifouling Surface

Multifunctional nanogel coatings provide a promising antimicrobial strategy against biomedical implant-associated infections. Nanogels can create a hydrated surface layer to promote antifouling properties effectively. Further modification of nanogels with quaternary ammonium compounds (QACs) potentiates antimicrobial activity owing to their positive charges along with the presence of a

Failure mechanism of copper antifouling coatings
