A Review on the Mechanical, Thermomechanical Properties and Crystallinity Aspects of 3D-Printed Nanocomposites Used for Fabricating Electronic/Structural Parts

Thermoplastic nanocomposites are fabricated without using solvents, i.e., by the melt extrusion method, and for this reason, this category of materials has a distinct advantage over thermoset nanocomposite materials. By using thermoplastic nanocomposites for fabricating engineering products, sustainability can be improved significantly. In addition, by adopting the additive manufacturing method, the wastage of materials can be reduced. In this short review, we report and compare the mechanical/thermomechanical properties of various 3D-printed thermoplastic nanocomposite materials. Structural integrity under operating conditions must be considered when designing electrical, electronic, or load-bearing components/products. Understanding the mechanical/thermomechanical behavior of the nanocomposite material before the design stage of the component/product is an important phase. A material having the combination of suitable properties can be selected according to the operating conditions. These nanocomposites are multifunctional, and a variety of applications can be developed, such as biodegradable electrical conductors, wearables, energy harvesters, antistatic closures, and bio-implants.
