dc.description.abstractEn | Monodisperse functional multiresponsive particles were prepared by encapsulation of an amphiphilic diblock copolymer during the precipitation polymerization of polystyrene and divinylbenzene in one single step. The amphiphilic diblock copolymer employed throughout this study, polystyrene-b-poly (dimethylaminoethyl methacrylate) (PS-b-PDMAEMA) has been synthesized by ATRP in two consecutive polymerization steps. After encapsulation of the block copolymer within the microsphere, the surface modification of the particle occurs spontaneously upon exposure to water by surface segregation of the hydrophilic PDMAEMA block, thus without any additional post-polymerization and/or chemical modification steps. The response of the functionalized particles both to pH and temperature was analyzed by potential zeta and DSC measurements. Upon dispersion of the particles in acidic media, the PDMAEMA block in its charged state is soluble and does not exhibit any change by heating. At higher pH values and temperatures above 35 °C (Low Critical Solubility Temperature of the PDMAEMA block) the hydrophilic segment collapses as detected by differential scanning calorimetry. | |
