Abstract
Reflective filaments were developed based on polycarbonate with the addition of 10-20 wt.% finely dispersed polytetrafluoroethylene (PTFE) powder and 5-15 wt.% titanium dioxide (TiO2) pigment. The manufactured materials can be used to obtain reflectors by 3D printing for use in scintillation technology, in particular as part of finely segmented plastic scintillators. The produced reflective layers have a reflection coefficient of up to 90% and a transmission coefficient of about 0.2% at the wavelength of the maximum emission of polystyrene-based plastic scintillator. Technical approaches to the production of scintillation elements with a reflector using additive technologies are also considered.
