Polymer composites enriched with conductive fillers hold immense potential for flexible pressure sensors, because of the remarkable piezoresistive effect they possess. Research on polymer composite pressure sensors has been actively ongoing because of their flexibility and high electrical resistance performance. This paper presents a comprehensive comparison of the piezoresistive characteristics..... More

Korean J. Met. Mater. 2022;60(10):793-799.   Published online 2022 Sep 29
DOI: https://doi.org/10.3365/KJMM.2022.60.10.793

For medical device and artificial skin applications, etc., large-area tactile sensors have attracted strong interest as a key technology. However, only complex and expensive manufacturing methods such as fine pattern alignment technology have been considered. To replace the existing smart sensor, which has to go through a complicated process, a..... More

DOI: https://doi.org/10.3365/KJMM.2022.60.9.694

To manufacture composites with required properties, it is extremely important to select an appropriate filler. Carbon-based nano materials such as carbon black, graphene and carbon nanotube (CNT) have been extensively investigated as reinforcing and conducting fillers. Because of their high aspect ratio coupled with superior physical properties, 1-dimensional CNTs are..... More

Korean J. Met. Mater. 2022;60(3):237-243.   Published online 2022 Feb 8
DOI: https://doi.org/10.3365/KJMM.2022.60.3.237

Recent studies have extensively studied the use of composites of carbon nanotubes (CNTs) dispersed in epoxy resin to mechanically reinforce hydrogen storage and lightweight vehicle applications. The mechanical properties of the composite are strengthened due to load transfer from the epoxy matrix to the CNTs when an external force is..... More

Korean J. Met. Mater. 2018;56(7):538-543.   Published online 2018 Jul 5
DOI: https://doi.org/10.3365/KJMM.2018.56.7.538

We report the effect of interface control using multiwalled carbon nanotubes (MWCNT) on thermoelectric properties of TiO2. By consolidating TiO2 nanoparticles with MWCNT (0.5, 1, 2, 4, and 8 wt%) using spark plasma sintering, we prepared interface-controlled TiO2-MWCNT nanocomposites, where TiO2 grains were surrounded with a MWCNT network. Simultaneous control of..... More
