Original language description
The addition of nanoparticles (NPs) into a polymer matrix represents a simple yet efficient tool for introducing or enhancing functional properties. 3D printing is a processing technique with unprecedented control over the micro-and macroscopic structure. Their combination creates a versatile fabrication tool for both professional and hobby users. However, some less intuitive effects brought about by NPs must also be considered. This study has thoroughly investigated the addition of bare and alumina-doped zinc oxide NPs into a representative free-radical photo-polymerization resin. The alumina doping suppressed the characteristic surface plasmon resonance of ZnO NPs. This absorption band was found crucial for the NP photoactivity and, subsequently, the conversion kinetics, post-curing, thermomechanical, and electric/dielectric properties of the nano-filled resins. Furthermore, three experimental techniques for assessing the photocuring kinetics - real-time FTIR, photo-DSC, and Jacobs working curves, were compared and resolved. Each yielded a completely different conclusion due to the photothermal effect and nanoreinforcement. The presented data shall aid with designing and testing of functional photo-polymer nanocomposites for 3D printing and other low-intensity curing applications.
