Measuring Thermal Conductivity of Conductive Plastics
The webinar will review related application areas of the TCi Thermal Conductivity Analyzer in assisting with the performance characterization of thermally conductive polymers. In highlighting recent published work from C-Therm clients – we will review research from around the globe, starting in South Korea. Researchers from Gachon University working with researchers in the USA from UCLA’s Dept of Mechanical and Aerospace Engineering investigated performance of different composite fabrication methods. High concentrations (1.1-3.7 wt%) of carbon nanotubes (CNTs) were incorporated into carbon fiber (CF)-reinforced epoxy composites. A mat-like form of CNT (CNT mat) was inserted between plies of CF plain-weave fabric and the composite was processed by vacuum-assisted resin transfer molding (VARTM). Two similar CNT structures, CNT mat and buckypaper, were inserted between CF woven prepreg laminates and the corresponding CF prepreg composites were fabricated by curing either in an autoclave or in a hot press. For the final method, CNTs were directly grown onto CF plain weave fabric and hierarchical composites were fabricated from those CNT-CF fabrics by the VARTM method. The fabricated composites were characterized for their improved thermal conductivity.
In addition, previous published nano-related works will be reviewed from Texas Tech and Florida StateUniversities on improving the dispersion of single-walled carbon nanotubes for greater thermal conductivity via physical and chemical treatments of the SWCNTs.
Finally, the webinar will conclude in reviewing works from the School of Materials and Mineral Resources Engineering at the Universiti Sains Malaysia employing the TCi Thermal Conductivity Analyzer. Researchers in Malaysia worked with surface-functionalized multi-walled carbon nanotubes (MWNTs) for improved thermal conductivity of poly(dimethyl siloxane) (PDMS).
The webinar will be of particular interest to any material engineers or scientists in the field of conductive polymers.
