Abstract:
1. A method of making an antioxidant-doped homogenized cross-linked consolidated interlocked hybrid polymeric material comprising the steps of: a) providing a polymeric material in a powder form; b) doping the polymeric material with an antioxidant without using a supercritical fluid, thereby forming an antioxidant-doped polymeric material; c) annealing the antioxidant-doped polymeric material from step b) in a supercritical fluid, thereby forming an antioxidant-doped homogenized polymeric material; d) heating and pressurizing the heated antioxidant-doped homogenized polymeric material under 10-1000 MPa to a counterface of a second material, thereby forming a hybrid material having an interface between the polymeric material and the second material; e) holding at the pressure and temperature; f) cooling the heated polymeric material; g) releasing the pressure, thereby forming an antioxidant-doped homogenized interlocked hybrid material; and h) irradiating the antioxidant-doped homogenized hybrid material by ionizing radiation, thereby forming an antioxidant-doped homogenized cross-linked interlocked hybrid material.
