摘要：
The effect of solids concentration on the adsorption and conformation of polymers at solid/liquid interface was investigated using depletion adsorption and fluorescence techniques. The fluorescence of pyrene labeled polyethylene oxide at silica/water interface as a function of solids concentration revealed a surprisingly measurable change in polymer conformation as the solids content was increased. Adsorption density as well as coiling of the polymers was found to decrease with increase in solids concentration. These changes are correlated with the rheological behavior of the suspensions.
