Studying concussions is of paramount importance. Concussions occurring in sports and sudden other accidental cases are causing major injuries to people often times it leads to CTE and eventual death. Chronic Traumatic Encephalopathy (CTE) is one type of degenerative brain disease that can be found in athletes, military veterans, and other people who have repetitive brain trauma. CTE is usually caused by repetitive hits to the head sustained over a period of years, most people diagnosed with CTE suffered hundreds or thousands of head impacts over the course of many years, such as playing contact sports or serving in the military. PDMS-based nanomaterials are gaining widespread attention in this regard. We report the use PDMS polymer and graphene oxide/graphene as nanoparticle reinforcement to produce the vibration-absorbing PDMS-graphene nanocomposite. The stiffness of PDMS and graphene-PDMS nanocomposites were measured using dynamic mechanical analyzer. We prepared a well-controlled pore containing PDMS-graphene nanocomposites that exhibited significant improvement in impact absorption properties as a function of porosity. Visual Molecular Dynamics (VMD) was used to compute the physical interactions between graphene and PDMS
