Carbonized biopolymers as a new class of environmentally friendly thermostabilizing modifiers of siloxane rubbers
Abstract
The introduction of hybrid nanocomposites with graphene particles in which surfaces are modified by nano-dispersed SiO 2 significantly improves the thermal stability of siloxane materials. By carbonizing rice husk using a tailored method of self-propagating high-temperature synthesis, a hybrid nanocomposite, low-layer graphene/SiO 2 , was obtained. Upon the incorporation of carbonized starch and carbonized rice husk into rubber mixtures based on polydimethylsiloxane, the vulcanization proceeded at an increased rate with a longer induction period. The resulting experimental mixtures were used to produce rubber samples subjected to physical and mechanical testing before and after thermal aging for 72 h at 250 °C in order to determine their elastic and strength characteristics. Overall, the outcomes of these tests confirm the effectiveness of the synthesized additives as thermal stabilizers for siloxane rubbers.
