“…The methods not only provided energy dispersive X-ray (EDX) in determining the presence of important element which was cloisite in SP/e-spunCL membrane but also the exfoliation images of surface membranes. Although the methods only provided the information on a small area which was not representative of the overall microstructure, regardless of all, SEM, FESEM, and XRD are very crucial analyses in evaluating morphology of nanocomposites [17].…”

One of the main problems in direct methanol fuel cell (DMFC) application is methanol crossover. In order to solve the problem, an exfoliated void-free electrospun Sulfonated Poly(Ether Ether Ketone) (SPEEK)/cloisite nanocomposite membrane was developed. The membrane was prepared by immersing electrospun SPEEK/cloisite fiber mats onto incomplete solidified SPEEK polymer matrix. A well dispersed and reduction size of cloisite particles that ranges from 0.29–0.39 µm was observed by using Scanning Electron Microscopy Analysis (SEM) and Atomic Force Microscope (AFM). The effect of the morphology of the composite membrane in terms of degree of dispersion state of the Cloisite on the membrane performance was discussed. SP/e-spunCL15 with fully exfoliated structure exhibited the highest performance as compared to other tested membranes and Nafion® 115 with current density of 1042.2 mAcm−2 and power density of 1.18 mWcm−2. Improved morphological, dimensional change properties, and performance assigned to well-dispersed cloisite15A induced by the electrospinning technique make the membranes more efficient for direct methanol fuel cell applications.

“…Suitable surfactants [8], polymers [9] and biomolecules [10] are commonly used as modifiers. Recently, it was demonstrated that pigment particles [11], carbon black [12] and CNTs [13] may be efficiently dispersed with the help of charged clay particles. Particularly, it was shown that introduction of charged nanoparticles (e.g.…”

Hybrid nanofillers composed of different ratios of carbon nanotubes (CNTs) and sodium montmorillonite (MMT) were prepared by physically pulverizing both materials in powder form. Their dispersion behavior was investigated in different solvents (water, toluene and carbon tetrachloride). UV-vis spectroscopy showed that the absorbance at 550 nm for the CNTs becomes more intense with the increasing amount of added MMT, when water is used as a solvent, implying their improved dispersion. This is not so evident for toluene and carbon tetrachloride. TGA analyses showed that the thermal stability of the hybrid nanofillers increases with the increase of the MMT content. Raman spectroscopy confirmed the mutual interaction between CNTs and MMT, demonstrated by shift of D and G band with addition of MMT in the nanofiller.
