In situ polymerized nanocomposites: Polystyrene/CNT and Poly(methyl methacrylate)/CNT composites

A series of polymer-matrix composites were synthesized by using a variety of carbon nanotubes (single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs) and multi-walled carbon nanotubes (MWCNTs)) and a polymer matrix (either polystyrene (PS) or poly(methyl methacrylate) (PMMA)). Different surfactants and polymerization methods were also used in order to generate a wide range of different composites. These different composites were all tested for thermal and electrical conductivity and characterized ...

Experimental and Model Research on Nanorefrigerant Thermal Conductivity

Describes how second-order terms are important to the hot-strip method, and should be included in situations where a high-current pulse is being used. The authors determined approximate values for the coefficients of second-order terms....

Evaluation of thermal and moisture management properties on knitted fabrics and comparison with a physiological model in warm conditions

Through the use of thermal conductivity and moisture related measurements, this article investigates the physical properties of undergarments of different compositions (cotton, polyester, rayon, viscose, etc.). This research is used to determine which types of materials would best be suited for use in sports/day-to-day/comfortable clothes. Important properties measured include the porosity of the material as that affects the ability for moisture to be released, as well as the ...

Determining the thermal conductivity of liquids using the transient plane source method. Part I: Establishing transient thermal-fluid constraints

The authors look into problems with accurately measuring thermal conductivity of liquid samples. Among these problems is the onset of natural convection during the measurement of thermal properties, which may lead to skewed values reported after characterization. The effect of natural convection is analyzed numerically for the transient plane source method in order to determine at what time during an analysis the convection causes incorrect output data. The effect of ...

Improving the thermal conductivity and shape-stabilization of phase change materials using nanographite additives

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 ...
