Modification of diamond-like carbon coatings with fluorine to reduce biofouling adhesion

Design of intelligent surfaces for energy intensive processing industry

“…However, the different coatings also produced a different level of roughness on the surface -with a strong correlation found between the number of adhering cells and the surface roughness. Fluorinated DLC has also been found to have antibiological properties in regards to decreasing surface adhesion as well as increasing the removability of adhered cells [128,129]. This became more pronounced as the proportion of F content was increased in the coating, as it was found to reduce the surface energy of the surface [128].…”

This became more pronounced as the proportion of F content was increased in the coating, as it was found to reduce the surface energy of the surface [128]. The C-F bond is believed to decrease the dielectric constant and the cross-linked C-C bonds contribute to the materials thermal stability [129].…”

“…sample performing the best (67% reduced adhesion & 32% increased removal compared to DLC). In addition to the decrease in surface energy with increasing fluorine content [128], structure of the film coatings also became more like a polymer structure than diamond like [129].…”

Molecular characterization of silver–stearate nanoparticles (AgStNPs): A hydrophobic and antimicrobial material against foodborne pathogens

“…In this respect, the use of self-cleanable surface or packing materials incorporated with special coating materials appears to be very promising approach to avoid such drawbacks. Accordingly, a couple of recent studies have shown that strong hydrophobic coatings could have a potential to minimize microbial adhesion to solid substrates (Crick et al, 2011;Lai et al, 2012;Nosonovsky and Bhushan, 2009;Su et al, 2010). The reason is attributed to the lotus effect in association with the stream of liquid such as water (Epstein et al, 2012).…”

Silicon nitride films for the protective functional coating: Blood compatibility and biomechanical property study

“…Diamond-like carbon (DLC) (Wan et al, 2007;Wang et al, 2004), carbon nitride film (Wang and Jiang, 2009), fluorinedoped and silicon-incorporated DLC films (Saito et al, 2005;Su et al, 2010;Roy et al, 2009) are widely used in many kinds of blood contacting medical devices. However, the limited understanding to-date of the role of deposition technique, coating composition, and coating surface properties on the biological performance of the coatings has been a barrier to their optimization for a given biomedical application.…”
