โฆ Synopsis
Alcohols between 1-18 carbon atoms, were grafted onto the surface of carbon blacks. The behavior of these grafts was studied essentially by two techniques: measurement of adsorption isotherms of water and liquid flow adsorption microcalorimetry. The results show that the surface properties of the grafted carbon blacks are influenced by two factors: the surface polarity of the carbon blacks and the conformation of the grafts.
