Retention And Stability Of Polystyrene Sulfonic Acid And Polyethylene Glycol Anti- Fouling Films With 3-Aminopropyltriethoxysilane Coupling Agent, Brian Cameron
Williams Honors College, Honors Research Projects
Fouling is a process where particles, proteins, or microorganisms will accumulate onto a material [2]. This can lead to biofilms in medical implants, which can trap and create drug resistant bacteria [5]. Due to this, the study and creation of anti-fouling polymeric films that is stable in aqueous environments is essential. The goal of this study is to utilize APTES to retain the already studied PSS-PEG anti-fouling films. The films that are created is a thermally crosslinked network of the polystyrene sulfonic acid (PSS) and polyethylene glycol (PEG) with differing mass fractions (75- 25 and 55-45 PSS-PEG). To retain the …

Effects Of Crosslinking Conditions On Biofouling Of Polymer Substrates With A Hydrogel Layer, Laura Davila

The introduction of a hydrogel coating to a surface has been looked at for different benefits. Certain hydrogels offer antifouling properties that are beneficial to different applications like medical components. Previous attempts (2) (3)have been done to introduce a hydrogel surface to plastic substrates. One of them is to use grafting brushes which works properly but it is not sufficient since the layer is too thin and therefore can be damaged. The second method have a bulkier coating without crosslinking. Opposite to grafting brushes this method has too thick of a layer. Additionally, there is no crosslink therefore the coating …
