A series of fabrics containing different mass ratios of polyurethane binder to melamine-formaldehyde microcapsules were created and their thermal properties were investigated. A variety of thermal analysis methods including guarded hot plate and differential scanning calorimetry were employed to characterize the series of fabrics. The mass ratio of microcapsules to polyurethane binder had a significant effect on the thermal properties of the fabrics and the researchers pointed out a specific ...
PANI/tetradecanol/MWNTs composites were prepared via in-situ polymerization and analyzed for their use as phase change materials. The MWNTs were randomly dispersed in the composite and it was determined that the PCM was form-stable and that phase separation of the MWNTs and PANI/tetradecanol wouldn't occur....
The low thermal conductivity of paraffin hinders its ability to be used as a PCM, and so in this article the authors created a composite made up of paraffin and micron-size graphite flakes (MSGFs) in order to hopefully increase thermal conductivity and energy storage capabilities. The results showed that increasing concentrations of MSGFs corresponded to 'enormous' increases in thermal conductivity. The addition of MSGFs to paraffin did not affect its ...
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....
Two different sets of phase change materials were made by adding either graphene or exfoliated graphite nanoplatelets (xGnP) to paraffin in hot toluene. The thermal and stability properties of these newly synthesized composites were then studied using the TPS method. The addition of xGnP led to a higher thermal conductivity while the addition of graphene led to a higher electrical conductivity. Graphene was found to be better at stabilizing the ...
