Paraffin confined in carbon nanotubes as nano-encapsulated phase change materials: experimental and molecular dynamics studies

Abstract

The characteristics of paraffin confined in carbon nanotubes (CNTs) were investigated using experimental and molecular dynamics (MD) methods.

Synthesis and Characterization of Paraffin/Metal Organic Gel Derived Porous Carbon/Boron Nitride Composite Phase Change Materials for Thermal Energy Storage

“…In addition, the FT‐IR spectra of the prepared composites displayed all the prominent absorption bands of pristine samples (Figure d–f). Five prominent characteristic peaks at about 2917 (asymmetric C‐H stretching of CH 2 ), 2849 (symmetric C‐H stretching of CH 3 ), 1463 & 1378 (C‐H bending vibration) and 719 cm –1 (rocking vibration of CH 2 ) are depicted due to the spectra of pristine PCM . While two major absorption bands of BN at about 1380 and 806 cm –1 due to B–N stretching and B–N–B bending vibrations, respectively, are displayed.…”

Thermal conductivity enhancement of paraffin by adding boron nitride nanostructures: A molecular dynamics study

“…However, the low thermal conductivity of paraffin seems to greatly restrict its further developments and applications in the large scale. Thus, a mass of researches and investigations have been carried out and performed in order to enhance the thermal conductivity [5][6][7][8][9][10][11][12][13][14][15][16][17].…”

A novel forced separation method for the preparation of paraffin with excellent phase changes

“…The carbon atom distribution of normal paraffin determined the quality of PCMs. 21,22 As shown in Fig. 4, there was no signicant change in the carbon atom distribution, most of which was concentrated between C 32 and C 33 in raw paraffin and the fractions from the forced separation of the paraffin products.…”
