We here present an effective strategy to prepare enhanced composites using poly(vinyl alcohol) (PVA) and multiwalled carbon nanotubes (MWCNT). It contains two essential steps. First, the elaboration of homogeneous aqueous MWCNT dispersions and the selection of the most effective dispersing agent. In a sequential dispersion protocol for seven common dispersants, including surfactants and polymer...

Since the discovery of carbon nanotubes (CNTs), researches of field emission display (FED) have been mainly focused on it, because of their high-aspect configuration, low work function, high mechanical stability and high conductivity. For CNTs to become a viable engineering material for FED applications, efficient assembly and integration processes for large size are required that are currently...

This study aims to determine the % solid content determination of concentration dispersing agent / leveler. Therefore, in order correct concentration, varied, namely 43.930%, 21.975%, and 14.650%, with each dispersing/averaging 0 g/l, 0.5 0.75 g /l, 1.5 g/l. Furthermore, preliminary testing power was carried out before immersion application. The results most optimal test were obtained at a vari...

stable homogeneous dispersions of carbon nanotubes (cnts) were prepared using ethanol as dispersing agent. then, using sol-gel method, dispersion in the hydroxyapatite matrix and its effects on the microstructure were investigated. the phase composition, chemical structure and morphological and size analyses were performed using xrd, ft-ir, sem, tem/saed/edx and raman spectroscopy. the influenc...
