Effect of Thermal and Mechanical Characterization of Titanium Dioxide Incorporated in Polyetheretherketone Materials

Considering the debonding of titanium dioxide (TiO2) fillers degrade the otherwise excellent antifatigue functions of polyetheretherketone (PEEK) materials, researchers are looking into polyetheretherketone-titanium dioxide nanocomposite composites as an opportunity to improve the bonding between both substances. TiO2 nanoparticles up to 1.5 weight per cent are successfully added to the PEEK matrix during the process of compounding and injection moulding processes for producing the nanocomposites. Measurements employing X-ray diffraction (XRD) and differential scanning calorimetry (DSC) are employed and designed for assessing the phase structure and crystallization composites. When the composites' physical features are assessed, it is found that at 1 weight per cent TiO2, their tensile strength is 96 MPa. The research work suggested that debonding structure among PEEK matrix and well-dispersed TiO2 nanoparticles were not present, presenting an alternative approach to the PEEK-TiO2 composites' debonding challenge.
