Polyhydroxybutrate filled clamshell biofiller: effect of polyvinylpyrrolidone
A totally green biocomposite was prepared via melt blending technique by using polyhydroxybutyrate (PHB) as a matrix, clamshells powder (CaCO3) as a reinforcing filler and polyvinylpyrrolidone (PVP) as a binder. PHB/CaCO3 was fixed at 70:30 ratio and PVP weight content varied at 3, 5, 7 and 9 wt%...

| description | A totally green biocomposite was prepared via melt blending technique by using
polyhydroxybutyrate (PHB) as a matrix, clamshells powder (CaCO3) as a reinforcing filler and
polyvinylpyrrolidone (PVP) as a binder. PHB/CaCO3 was fixed at 70:30 ratio and PVP weight
content varied at 3, 5, 7 and 9 wt%. The properties of the biocomposite have been studied in term of
mechanical properties and morphology. The results showed that incorporation of PVP increased the
tensile modulus which remarkably demonstrated by the enhancement in stiffness of the biopolymer.
While, elongation at break decreased in an opposite behavior. Surface morphology observation on the
tensile fracture samples shows the presence of microvoids, due to binding effect of the PVP. |
