Mechanically Robust Nanocomposites from Screen-Printable Polymer/Graphene Nanosheet Pastes

Abstract

Innovative methods producing graphene-based polymer nanocomposites with excellent mechanical robustness have become a focus on practical utilization, but existing solutions suffer from drawbacks such as laboratory-scale, unaffordability, and inadequate processability. To address those issues, we proposed screen printing approach utilizing formulated graphene-modified water-based printable pastes to achieve inexpensive and scalable manufacturing of graphene-reinforced polymer nanocomposites. Leveraging this simple and versatile manufacturing process, not only mass production but also individualized-patter bulk materials can be efficiently produced using easily obtainable substrates. The surface-tailored graphene (PEI-rGO) can improve the dispersion quality and strengthen the interfacial bonding with waterborne polyurethane (WPU) matrix, yielding optimized enhancement effect and then enhancing the tensile strength and Young’s modulus about 9.46 and 19.8 times relative to that of the pure WPU, respectively. In particularly, their utility as anti-wear modifier through direct printing on textile and wear-reduction performance were investigated. Beyond such, our study establishes screen printing as a general strategy to achieve facile fabrication of polymer nanocomposites in an industrial-scale and economically viable manner, which can to a great extent bridge the gap between scientific research and real-world applications.
