Περίληψη:	The associative, thermoresponsive and complexation properties of the triblock terpolymer PnBA-b-PNIPAM-b-PAA are explored in aqueous solutions. Using light scattering and small angle neutron scattering PnBA-b-PNIPAM-b-PAA is found to self-organize in aggregates of interconnected chains that are incorporated in larger clusters. Upon temperature increase the aggregates increase in molecular mass and shrink due to the enhancement of the hydrophobic interactions during the hydrophilic-to-hydrophobic transition of PNIPAM. In this state the well-defined aggregate interface gives rise to inter-aggregate spatial correlations. Remarkably the incorporation of lysozyme globules induces spatial correlations even at room temperature and controls the aggregate interconnections and mutual arrangement by tuning their surface charge and roughness. This system may be considered as a multicomponent, multifunctional super-structure with tunable morphology that combines the properties of synthetic and biological macromolecular components.
