Abstract Details

2022, Master of Sciences (Engineering), Case Western Reserve University, Biomedical Engineering.
This study investigated the effects of Ar/H2O plasma treatment on the surface and bulk properties of polytetrafluoroethylene (PTFE) and polyethylene terephthalate (PET) surgical mesh materials as a method to modify and mitigate biofouling events that reduce their performance. With regards to bulk properties, findings from uniaxial tensile testing of these substrates in mesh and suture form show that plasma treatment can weaken their tensile properties. Increasing treatment duration and surface area to volume ratio were found to be major factors that resulted in further reduction of these properties. With regards to surface properties, the direct application of plasma on these substrates was not found to reduce biofouling in the form of protein adsorption and S. aureus attachment compared to untreated control surfaces. These experiments suggest that the deposition of a subsequent coating after plasma treatment is needed to further control biofouling events and is a future direction worth investigating.
