Experimental and modeling of thermal and dielectric properties of aluminum nitride-reinforced polybenzoxazine hybrids

Compared to traditional epoxy, polybenzoxazine resins have improved thermal, mechanical, and electrical properties. In this article, spherical aluminum nitride (AIN) was studied as a filler in bisphenol A-aniline-based polybenzoxazine (poly(BA-a)). Thermal conductivity was obtained by transient plane source method. Thermal conductivity of each composite gradually increased with enhanced filler amount. Poly(BA-a)/AIN composites also had higher thermal conductivity than systems containing epoxy/AIN....

One-pot synthesis of light-driven polymeric composite phase change materials based on N-doped porous carbon for enhanced latent heat storage capacity and thermal conductivity

Polymeric composite materials were prepared by one-pot synthesis of chromophoric polymer phase change material in nitrogen-doped porous carbon (NPC). Thermal conductivity was found to increase with increasing NPC wt%, enhancing the heating rate with a shorter phase change period....

High thermal conductive m-xylylenediamine functionalized multiwall carbon nanotubes/epoxy resin composites

Thermally conductive polymers are the most effective and economic methods of removing heat accumulation from microelectronics. In the present study, m-xylylenediamine (MPDA) was used as a curing agent for the epoxy matrix and analyzed for its effect on the thermal conductivity of the composite. Thermal conductivity was measured with a thermal analyzer using the transient plane source (TPS) method. When filling content of the multiwall carbon nanotubes (MWNTs) was 2%wt, ...

Reaction to fire of an intumescent epoxy resin: Protection mechanisms and synergy

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 ...

Synergistic effect of BN and MWCNT hybrid fillers on thermal conductivity and thermal stability of ultra-high-molecular-weight polyethylene composites with a segregated structure

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 ...
