Biodegradable polyhydroxybutyrate as a polyol for elastomeric polyurethanes

Popis výsledku v původním jazyce

In the proposed work, new elastomeric bio-polyol based polyurethanes (bio-PUs) with specific mechanical properties were prepared by a one-shot process without the presence of a solvent. Commercial non-degradable polyether polyol derived from petrochemical feed stock was partly (in the amount of 1 mass %, 5 mass %, and 10 mass %) substituted by the biodegradable polyhydroxybutyrate (PHB). Morphology of elastomeric PU composites was evaluated by scanning electron microscopy and mechanical properties of the prepared samples were obtained by both tensile measurements and prediction via the Mooney-Rivlin equation. Electron microscopy proved that the prepared materials have the character of a particle filled composite material, where PHB particles are regular with their size of about 1?2 microm in diameter. Tensil measurements demonstrated that the Youngs modulus, tensile stress at break, and tensile strain at break of each sample increase with the increase of the volume fraction of the fill
