Title : Hybrid nano filaments of superior strength for polymer natural fiber reinforced composites

Abstract:

Human-made natural-fber-based flaments are attractive for natural fber-reinforced polymer (NFRP) composites. However, the composites’ moisture distribution is critical, and humidity monitoring in the NFRP composites is essential to secure stability and keep their life span. In this research, high strength and humidity sensing flament was developed by blending cellulose nanofber (CNF) and graphene oxide (GO), wet-spinning, coagulating, and drying, which can overcome the heterogeneous mechanical properties between embedded-type humidity sensors and NFRP composites. The stabilized synthesis process of the CNF-GO hybrid flament demonstrated the maximum Young’s modulus of 23.9GPa and the maximum tensile strength of 439.4 MPa. Furthermore, the achieved properties were successfully transferred to a continuous fabrication process with an additional stretching process. Furthermore, its humidity sensing behavior is shown by resistivity changes in various temperature and humidity levels. Therefore, this hybrid flament has excellent potential for in-situ humidity monitoring by embedding in smart wearable devices, natural fber-reinforced polymer composites, and environmental sensing devices.
