Polyurethane (PU) nanocomposite films were prepared through a solution casting technique slightly modified by individual and simultaneous additions of proper nonsolvent (ethanol) graphene nanoplatelets. To this end, different contents functionalizations (hydrophobic hydrophilic) used to modify the surface properties PU make it more biocompatible. X-ray diffraction patterns revealed that both ty...
Double-walled polyurethane/poly(urea-formaldehyde) microcapsules (PU/UF) are prepared for use in self-healing materials. This modified encapsulation procedure combines two chemistries to form more robust capsule shell walls in a single operation. Robust capsules are formed by this procedure as long as the aromatic polyisocyanate prepolymer is soluble in the core liquid and the core liquid is co...
An irreversible loss of subcutaneous adipose tissue in patients after tumor removal or deep dermal burns makes soft tissue engineering one of the most important challenges in biomedical research. The ideal scaffold for adipose tissue engineering has yet not been identified though biodegradable polymers gained an increasing interest during the last years. In the present study we synthesized two ...
