Currently, we have been able to create polymers using hydridosiloxanes (high thermal stability) and divinylbenzene (high mechanical stability) using a platinum based catalyst. As expected, the resulting polymer had a combination of the two monomers characteristic strengths. The mechanical properties of the polymer were seen through the result of a stress and a strain test. By applying weight to the top surface of the polymer we were able to calculate the compressional stress also called normal stress. This is the force perpendicular to the surface of the polymer which acts to compress it. The deformation in the polymer’s height and shape relative to its original quantities is called the strain. The change in height allowed for the calculation of stress: Newtons per square meter (Force per unit area). A plot between stress and strain yielded a linear line indicating that there is a proportionality between the two, following Hooke’s law.
Looking forward, we would like to bring this research project more in line with my major, Biochemistry. Working in collaboration with the research group of Dr. Wier in the biology department, we will be analyzing the growth of biofilm forming bacteria on these hydridosiloxane-divinylbenzene polymers with varying amounts of zinc ions (Zn2+) suspended in the crosslinked polymer. Studies have backed up the effectiveness of zinc oxides antimicrobial properties on the surface of titanium implants used in dental system applications. The formation of zinc oxide on the surface of polymers can extend the usefulness of surface embedded zinc due to polymers being used in many more applications.
