The GnF/SU-8 composites are new polymer matrix composites (PMCs) composed of graphite nanoflakes (GnFs) bound together by SU-8 photoresist. The PMCs therefore have excellent ultraviolet (UV) photopatternability and high electrical properties. In spite of the unique material properties of GnF/SU-8 composites, much still remains uncertain about their controllability in both UV photopatternability and electrical properties. Here, we investigate 7 kinds of GnF/SU-8 composites having different GnF concentrations of 5.0 to 25.0 wt.% to characterize the changes in the UV photopatternability (i.e., polymerized thickness and photopattern quality) and electrical conductivity of GnF/SU-8 composites caused by a variation in GnF concentration. The polymerized thickness of GnF/SU-8 composites is measured to be in the range of 4.06 to 23.99 μm, which is inversely proportional to GnF concentration and also directly proportional to UV dose (i.e., 345 to 3,450 mJ/cm2) because of the screening effect of GnF existed in the composites; the photopattern quality at the edge is in inverse proportion to GnF concentration. An increase in GnF concentration leads to a significant change in the electrical conductivity of GnF/SU-8 composites in a proportional way (up to 25.34 S/m). The GnF/SU-8 composites are expected to be widely used as UV photopatternable and electrically conductive PMCs for diverse engineering applications.

AbstractThere are few studies that discuss the effect of the fabrication conditions and bulk thickness on the electrical conductivity of hot pressed polymer-matrix composites. For polymer-matrix composites that possess a segregated-network microstructure, the processing parameters can significantly impact the electrical properties and microstructure of the composite material. Our group has recently fabricated novel polymer-matrix nanocomposites, which possess a segregated network microstructure containing regular, polyhedral-shaped polymer matrix particles1-2. This paper investigates the effect of processing pressure and specimen thickness on the electrical properties and microstructure of hot pressed poly(methyl methacrylate) (PMMA) containing segregated networks of indium tin oxide (ITO) nanopowders.
