Constructing self-assembled hybrid particles of graphite oxide and zirconia nanoparticles significantly reinforced the properties of phenolic resin, improving bending strength, impact resistance, residual carbon rate, and friction and wear performance.
Phenolic resin modified by common physical methods cannot be applied directly in the military and aerospace fields due to its brittleness, poor heat resistance, and poor friction and wear resistance. Here, a strategy to significantly reinforce these properties was proposed by constructing self-assembled hybrid particles of graphite oxide (GO) and zirconia (ZrO2) nanoparticles to modify phenolic resin. The bending and impact test results showed that the bending strength, bending modulus, and impact strength maximumly increased by 73.6%, 52.3%, and 115.3%, respectively. The thermogravimetric analysis showed that the residual carbon rate increased by 19.7%, and the temperature T-d,T- max at the fastest thermal decomposition rate increased by 18 degrees C. The friction and wear tests showed that the friction coefficient and wear rate reduced by 27.7% and 64.8%, respectively. The modified phenolic resin has met the applicable standards in military and aerospace fields. This strategy is also applicable to the performance reinforcement of other polymers.
