A series of melamine-formaldehyde microcapsules were synthesized using an in-situ polymerization and subsequently characterized for their thermal and structural properties. SEM and FT-IR were used to investigate the structural properties and DSC and TGA were used to investigate the thermal properties. The authors concluded that the thermo-physical properties of the microcapsules were related to the synthesis conditions and the core content of the capsules....
The authors created a series of composite latent storage materials (CLSM) using expanded graphite (EG) and a two different metal nitrate phase change materials (K and Li, K and Na). The steady-state comparative method was used in order to measure thermal conductivities because it was deemed the best technique. Properties investigated that were related to the effective thermal conductivity were material temperature and microstructure and their effect on thermal conductivity....
Different concentrations of boron nitride (BN) were added to novolac resin in order to create a composite and modify the thermal conductivity which increased with increasing BN concentration. An instrument was used for the thermal conductivity measurements. Different size BN particles were also explored. The Maxwell-Eucken model was used to predict values which aligned well with experimental results....
Through the addition of graphite powder (GP) and expanded graphite (EG) the authors were able to increase the thermal conductivity of a shape-stabilized paraffin/high density polyethylene (HDPE) composite phase change material (PCM). GP and EG were added in different mass fractions and a Thermal Constants Analyzer was used in order to measure the thermal conductivity. The relationship between mass fractions of GP and EG added were found to have ...
As electronic devices become smaller, power densities increase and so do hotspot temperatures, leading to a need for materials that can exchange heat better. The materials that facilitate this heat exchange are called thermal interface materials (TIMs). Graphene has been shown to demonstrate superior thermal conductivity and a particular form called few-layer graphene (FLG) was used in this project. A novel TIM was created by the mixing of a silver ...
