Electrospun Mats of Fluorosiloxane Copolymers with Antifouling and Antibacterial Performances.
Background: The adsorption and accumulation of biomolecules and microorganisms on materials can significantly shorten the service life of materials. Fibrous materials featuring hydrophobic and anti-protein adsorption properties are urgently required for numerous applications, particularly in environments requiring liquid repellency and biofouling resistance.
Methods: In this work, electrospun fibers are fabricated via the electrospinning of fluorosiloxane copolymers of methyl methacrylate (MMA), isobornyl methacrylate (IBMA), and methacryloyl-terminated poly[methyl(3,3,3-trifluoropropyl)siloxane] (PMTFPS-MA). Porous microstructures are achieved by adjusting the composition and concentration of the spinning solution.
Results: The resultant electrospun fiber mats exhibite high hydrophobicity and self-cleaning properties, owing to their multi-scale surface roughness resulting from porous microstructures. Moreover, the combined effects of the fouling release of PMTFPS and the surface stereochemistry of IBMA significantly endow the mats with superior protein-resistant and antibacterial properties.
Conclusions: These hydrophobic electrospun fiber mats are promising candidates for applications requiring hydrophobic fibrous materials.
