Effect of carbon nanoparticles on selected properties of hot melt adhesives
Abstract
Electrically conductive adhesives are a group of materials developed to be used as adhesives in electronics or the aviation and automotive industry as a bonding medium of thermoplastic or thermosetting matrix composites. They consist of an adhesive, which lately the thermoplastic ones become more popular than the epoxy-based, and conductive fillers such as carbon nanotubes, carbon black, graphene, or metal powders.In this research,the electrically conductive adhesives were fabricated from the low-temperature copolyamide hot melt, multi-walled carbon nanotubes, and graphene flakes. The dispersion and distribution of the carbon fillers in the polymer matrix were observed using a high-resolution scanning electron microscope. Thermal properties were determined by thermogravimetric analysis and differential scanning calorimetry. The effect of the carbon fillers on the tack and rheological properties such as viscosity, storage and loss modulus were identified by an oscillatory rheometer. The electrical conductivity of these new conductive adhesives was measured using a nano voltmeter, and the results were correlated with the fillers' state of dispersion. To analyze the bonding strength of the electrically conductive adhesives, the lap shear test was performed.
