Strain sensing in polymer/carbon nanotube composites by electrical resistance measurement

Multifunctional nanocomposites of poly(vinylidene fluoride) reinforced by carbon nanotubes and magnetite nanoparticles

“…Similar behaviour has been seen in PVDF based composites prepared by melt compounding, in which the incorporation of CNT produced transformation of the phase into ! phase [26,27]. Furthermore, the incorporation of Fe 3 O 4 nanoparticles in PVDF/CNT matrix slightly and gradually increases the !…”

Mechanical, flow and electrical properties of thermoplastic polyurethane/fullerene composites: Effect of surface modification of fullerene

“…Reinforcing ability of carbonaceous fillers is mainly related to mechanical performance and electrical conductivity improvement for polymer composite applications [10][11][12]. Incorporating nano-fillers in polymeric matrices has been applied in three different ways such as solution, in-situ and melt mixing.…”

MWCNT–Epoxy Nanocomposite Sensors for Structural Health Monitoring

“…At this point, the transition from the insulating to the conductive phase, called percolation threshold, is observed. The experimental method for the determination of the respective percolation threshold measurement was in compliance with the method used in [36]. Due to simplifications in the preparation process of the samples, the percolation threshold was achieved with samples containing a higher weight percent of CNTs.…”

“…In comparison to the specimens including 1 and 2 wt % MWCNT, the slope of the resistance changes diagram for the specimens with 3 wt % MWCNTs also exhibits a smoother shape. Georgousiset al [36] reported that the highest sensitivity can be achieved close to the percolation threshold. In the present study, we confirm these results showing that the smoothest curves are achieved above the percolation threshold.…”
