Polymer Microfibrillar Composites

Microfibrillar Composites

What is about?

Most common thermoplastic polymers remain immiscible in the melt phase. This immiscibility causes phase separation and low adhesion between two phases, which results in low mechanical properties. Today, studying the phase separation of polymer blends is of huge importance for determining the performances of new polymeric materials. The microfibrillar composite (MFC) concept was found as a convenient way to convert non-compatible blends into fiber reinforced composites and improve the final mechanical properties such as strength and stiffness.                                                          


Objective of the research

The goal of this research is to apply the MFC concept to recycled polymer waste streams. Considering that the most of recycled plastics is a mixture of polyolefins and PET, this concept could be utilized in a wide range of everyday applications due to their improved mechanical properties.
