Abstract

Amphiphile polymers find widespread applications because of their unique ability to self-assemble and modify interfacial properties. Smart polymers have very promising applications in the biomedical field as delivery systems of therapeutic agents, tissue engineering scaffolds, cell culture supports, bioseparation devices, and sensor or actuators systems. Polyurethanes and polyurethane-ureas based on Pluronic macrodiols have been prepared. The morphological and selfassembly characteristics were tuned in function of the structural parameters related to the soft matrix and H-bonding. HF plasma was employed to change the interfacial characteristics. The plasma action was evaluated by contact angle measurements. SEM and AFM analyses evidenced the microheterogeneous morphology and the self-assembling behaviour..
