This article investigates the effects of two types of nanoparticles, OctaMethylOligomericSilsesquioxanes (OMPOSS) and carbon nanotubes (CNTs), in a model epoxy resin. Intumescent phosphorous-based flame-retardant (APP) was also incorporated with the CNTs. Thermal conductivity of nanocomposites was measured using a thermal analyser with the transient plane source method. Epoxy with APP and OMPOSS had increasing thermal conductivity below the glass transition temperature (Tg) but slowed above Tg. When APP and CNTs ...
In efforts to develop polymers possessing high thermal conductivity, ultra-high-molecular-weight polyethylene (UHMWPE)/boron nitride particles (BNp), UHMWPE/BN sheets (BNs), and UHMWPE/(BN+MWCNT) hybrid filler composites were analyzed in this study. Thermal conductivity was measured using the transient plane source (TPS) method. Results show that conductive pathways were formed in the composites, increasing both the connection between particles and the thermal conductivity. BNp-filled UHMWPE composites had an overall higher ...
In this study, graphene nanoplatelets (GNP) and multi-walled carbon nanotube fillers (MWCNT) were simultaneously added to a polycarbonate matrix, in an attempt to improve thermal conductivity. Thermal conductivities of the composites were measured at room temperature. Results show that MWCNTs can improve thermal conductivity by filling gaps between GNPs. Additionally, a small amount of well dispersed MWCNTs increased thermal conductivity by 23% compared to composites containing only GNPs....
This study aimed at developing polymer-based dielectric materials with high charge-discharge efficiency and large energy density at high temperatures. A polymer nanocomposite was formed using c-BCB polymer matrix with two-dimensional hexagonal boron nitride nanosheets (BNNS). Using a transient technique, thermal conductivity was measured with a Thermal Analyzer. The incorporation of BNNS into PMMA was found to increase thermal conductivity and enhance properties of the nanocomposites....
This article aims at assessing the impact of rice husk ash and volcanic ashes on the processing of porous inorganic polymers. The addition of volcanic ash or rice husk ash in porous Inorganic Polymer Composites (IPC) allows for the reduction of sodium silicate necessary, improving the Si/Al ratio. Thermal conductivity was measured using an instrument through the transient plane source method. With the addition of aluminum content and rounded ...
