Tribological Properties of Carbon Nanotube and Carbon Nanofiber Blended Polyvinylidene Fluoride Sheets Laminated on Steel Substrates

Abstract

Nanostructured carbon dispersed polymer nanocomposites are promising materials for tribological applications. Carbon nanofiber (CNF) and carbon nanotube (CNT) dispersed polyvinylidene fluoride (PVDF) nanocomposite was prepared by chemical synthesis route. Morphology and microstructure of well-dispersed CNF and CNT in PVDF were specified by scanning electron microscope and X-ray diffraction, respectively. Moreover, chemical and functional characteristics were examined by Raman spectroscopy and FTIR investigation. The friction coefficient of PVDF nanocomposite laminated on steel substrate decreased with an increase in the dispersed quantity of CNF and CNT. The friction coefficient of PVDF is approximately 0.27; however, the addition of carbon nanomaterial in PVDF will further decrease the friction coefficient between 0.24 and 0.17. This value was significantly less in CNT dispersed PVDF nanocomposite. This could be explained by easy shearing and rolling action contact interfaces.

Current and future applications of PVDF-carbon nanomaterials in energy and sensing

“…In this case, small amounts (2-4 wt.%) of the above admixed nanoparticles increase YM, and, at the same time, the enhancement in thermal and electrical conductivity, hydrophilicity, and roughness are observed. Friction coefficient of PVDF can decrease after dispersion of carbon nanofiber and nanotubes [28].…”

Enhancing the Tribological Properties of Low-Density Polyethylene Using Hard Carbon Microfillers

“…Incorporating filler materials into polymer matrices is a widely employed strategy, renowned for its ability to improve both the cost-effectiveness and performance of composite materials. Notably, these particles or fillers have been shown to enhance various properties of polymers, including electrical, mechanical, and tribological characteristics [2][3][4][5][6][7][8][9][10][11][12][13]. In keeping with this approach, recently many researchers have explored a diverse array of inorganic and organic filler materials to bolster the mechanical and tribological characteristics of LDPE.…”

Numerical Analysis of the Influence of a Magnetic Field on the Group Dynamics of Iron-Doped Carbon Nanotori

“…Carbon nanotubes can be metallic or semiconducting [8] and have high heat capacity, thermal conductivity, thermal stability and fire resistance [9][10][11], and high tensile strength and Young's modulus [12][13][14]. Nanotubes find their application in electronics [15], optics [16], medicine [17][18][19], and materials science [20], allowing the production of nanodevices such as molecular probes, pipes, bearings, pumps, and so on.…”
