“…Normally, these water molecules are highly polar in nature which increases surface polarity of composite material. The same trend has been observed by Wu and Tung in the mineral filled epoxy composites. The dielectric properties of polymeric materials mainly depend on interfacial orientation as well as on electronic and atomic polarization .…”

The thermal and dielectric properties of municipal solid waste (MSW)/banana fiber composites were investigated as a function of total volume fraction of filler (MSW+ banana fiber). The relative volume fraction of MSW/banana fiber and its chemical modification was also investigated. The total volume fraction (Vf) of filler is established by keeping the relative volume fraction of MSW and banana fiber as 50:50. The thermal conductivity of composites decreases with increase of filler ratio. Subsequently, composites with different volume ratios of MSW and banana fiber (100:0, 75:25, 50:50, 25:75, 0:100) were prepared by keeping total Vf of filler as 50%. Low thermal conductivity and diffusivity values were obtained in composites with an MSW and a banana fiber ratio as 50:50. Moreover, chemically modified filler composites show decrease in dielectric constant, dielectric loss factor and an increment in volume resistivity. Experimental dielectric constant values are correlated with theoretical models. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 468–475, 2017

The electrical properties of mica-polystyrene composites were studied using the impedance measurements technique. The study was carried out as a function of frequency and mica concentration. It was observed that the AC conductivity and the dielectric constant are increased with increasing of the mica content in the composite. The observed electrical results fit approximately the reported empirical equations concerning the AC conductivity and dielectric behavior of polymer composites. Relaxation processes were observed to take place for composites having high mica concentration. The observed relaxation and polarization effects of the composite are mainly attributed to the dielectric behavior of the mica filler. However, the results were explained on the basis of the interfacial (space-charge) polarization, dipolar polarization and decrease of the hindrance produced by the polymer matrix.

The electrical properties of banana fiber-reinforced phenol formaldehyde composites have been studied with special reference to fiber loading, fiber treatments, and hybridization with glass fibers. The dielectric constant decreased with frequency and fiber loading. Treatments with silanes, NaOH and acetylation, latex treatment, heat treatment, and cyanoethylation decreased the dielectric constant value. The dielectric constant is higher for banana/PF composites than that of glass/PF composites. In hybrid composites, the dielectric constant decreased with increase in glass fiber concentration. The volume resistivity of banana fiber-reinforced phenol formaldehyde composites decreased with frequency and fiber loading. Chemical modifications in the fiber increased the volume resistivity of the composites. Volume resistivity of banana/glass hybrid composites increased with increase in glass fiber content. Layered composites with glass fiber at periphery were found to have higher volume resistivity than other layering patterns. The loss factor decreased by the chemical treatments and in hybrid composites it decreased with increase in volume fraction of glass fibers.
