Fouling is a process where particles, proteins, or microorganisms will accumulate onto a material . This can lead to biofilms in medical implants, which can trap and create drug resistant bacteria . 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 polymer film, the APTES (3-aminopropyltriethoxysilane) was mixed into the solution. Contact angle measurements analyzed with a simple T-test and visualization through photography and software, ImageJ, were used to measure retention. Generally, the contact angles for APTES treated films were greater than the controls but the p- values proved the averages to not be statistically impactful except for PSS-PEG 75-25 APTES treated films for both Advancing and Receding contact angle measurements and PSS-PEG 55-45 5.0% APTES for receding contact angle measurements. In general, the addition of APTES to the PSS-PEG polymer film led to greater retention but more studies are needed.
