Effect of mixed solvent and temperature on the the phase behavior of hydroxypropyl cellulose in the presence of sodium dodecyl sulfate
Smart materials, such as responsive aqueous foams, have gained considerable attention due their properties. These foams, for which the stability is sensitive to external stimuli, are of interest for several applications where both formation and destabilization of foams is required. Although thermoresponsive foams from synthetic polymers have been studied, poor results were achieved due to their instability and to the loss of responsiveness with temperature if mixed with sodium dodecyl sulfate (SDS). Our purpose is to study hydroxypropyl cellulose (HPC) as a green polymer alternative in mixture with SDS and glycerol to gain stable thermoresponsive foams. The comprehension of the structure of the HPC/SDS complex mixtures at the liquid-air interface should be related to the bulk complex with respect to the temperature is not clearly defined yet. SANS measurements are essential to define its morphology. Such measurements are limited, at the moment, to the bulk solution in preparation of future measurements on foams with a proper cell.
