Characterisation of the surface of a cellulosic multi-purpose office paper by i...
Santos, J. M. R. C. A.; Gil, M. H.; Portugal, A.; Guthrie, J. T.The surface of multi-purpose cellulosic office paper has been analysed by inverse gas chromatography (IGC). The parameters determined were the dispersive component of the surface free energy, the enthalpy of adsorption and the entropy of adsorption of polar and apolar probes, the Lewis acidity constant, Ka, and the Lewis basicity constant, Kb. It can be concluded that the dispersive component of the surface fre...
