Influence of 3D printed thermochromic additives on rheological properties of melt and mechanical properties of solid polymer

Thermochromism is subclass of chromogenic phenomena, where visible optical properties change dependence on temperature. This phenomenon could appear in thermoplastics, duroplastics, gels, inks or paints. Colour change of thermochromic materials could be reversible or irreversible. Thermochromic systems are widely used as a carrier in various applications such as smart packaging, security printing, toys and marketing. Thermochromic pigments and their incorporation into mass market polymers have become increasingly important in the art and textile application. With use of 3D printer, a variety of different products could be made. We will focus on use of PLA filaments with incorporated thermochromic pigment. The rheological, thermal, and mechanical properties of both commercial and extruded thermochromic polymer will be investigated.
