“…Minimum resistivity is observed for the maximum BST loading

. Absolute resistivity values are comparable to those reported for other BST/polymer blends [ 13 , 14 , 28 , 29 , 34 , 35 ]. Unfortunately, BST/ABS foils with higher

ratios cannot be acquired, since the produced foils are extremely fragile due to the very low ABS concentration.…”

“…Notably, the charge carrier conduction is severely affected by the presence of grain boundaries resulting in enhanced resistivity, as well as an increased Seebeck coefficient, with decreasing grain size [ 36 , 37 ]. Moreover, porosity also enhances the Seebeck coefficient [ 35 ], in contrast to the observed slightly reduced

values. Further investigation is required to clarify such a contradiction; however, it is beyond the scope of the current study.…”

In the current study, polymer-based composites, consisting of Acrylonitrile Butadiene Styrene (ABS) and Bismuth Antimony Telluride (BixSb2−xTe3), were produced using mechanical mixing and hot pressing. These composites were investigated regarding their electrical resistivity and Seebeck coefficient, with respect to Bi doping and BixSb2-xTe3 loading into the composite. Experimental results showed that their thermoelectric performance is comparable—or even superior, in some cases—to reported thermoelectric polymer composites that have been produced using other complex techniques. Consequently, mechanically mixed polymer-based thermoelectric materials could be an efficient method for low-cost and large-scale production of polymer composites for potential thermoelectric applications.

Three-dimensional (3D) printing has received extensive attention due to its unique multidimensional functionality and customizability and has been recognized as one of the most revolutionary manufacturing technologies. Functional 3D printed products represent an important orientation for next-generation manufacturing and attract a great spotlight for the application in sensors, actuators, robots, electronics, and medical devices. However, the lack of functions of printing polymeric materials dramatically limits the development of functional 3D printing. Different from traditional processing, the physical properties, such as geometry and rheological behavior, of the polymeric materials must match the printing process, making the selection of printable materials limited. More importantly, challenges in large-scale production of such materials further stifle the development of functional 3D printing industry. In this review, we aim to outline recent advances in polymeric materials and methodologies for the functional 3D printing technology. The reports are classified based on functionalities, including electronic conductive, thermally conductive, electromagnetic interference shielding, energy storage, and energy harvesting materials. This study attempts to provide a comprehensive overview of the challenges and opportunities for 3D printing functional polymeric materials/devices, also seeks to enlighten the orientation of future research in this field.
