The designing and characterization of polymer micro and nano-composites are based on native and recycled thermoplastic and thermosetting polymers suitably incorporating fillers of different size and shape, and additives that can improve compatibility between the components. The main objectives include a control on the processing and structure of the composites resulting in enhanced properties and effective practical application. Novel devices will be attached to the current technological equipment allowing more precise control of the processing and formation of reinforced or hybrid composites. The size and shape of the filler, the surface and interfacial interactions affecting the rheological, thermal, physico-chemical and mechanical properties of the composite materials are examined in details. Experimental results and theoretical predictions are correlated following the processing-structure-properties relationships. The study is performed in three Work packages:

  • Work Package 1. Recycling of secondary plastics: modification of polyethylene terephthalate, structure and properties. Coordinator: Assoc. Prof. Dr. Strashimir Djumaliisky
  • Work Package 2. Multicomponent material intended for the polluted sites rehabilitation. Coordinator: Assoc. Prof. Dr. Margarita Natova
  • Work Package 3. Development of technological assembling of energy-efficient pipes intended for outdoor mounting. Coordinator: Assoc. Prof. Dr. Margarita Natova
