Abstract

 

ABSTRACT
The manufacture of a biodegradable plastics film containing of polymer synthetic polystyrene
(PS) and biopolymer of polycaprolactone (PCL), poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
[P(3HB-ko-3HV)] and biodegradation study in ocean water has been carried out. Plastics film
containing of PS/PCL/P(3HB-ko-3HV) produced by blending techniques followed by solvent
casting with ratios were of 100/0/0, 95/5/0, 95/0/5, 90/5/5, 85/10/5, 85/5/10. This testing was
conducted based on immersion test method recommend by American Society for Testing and
Materials. Poly blend plastics film PS/PCL/P(3HB-ko-3HV) were characterized by tensile
strength, thermal properties and SEM analysis. The profiles of the rate biodegradation view by
weight reduction of the tested plastic film for 1-7 weeks period. Tensile strength analysis
showed the decreasing of tensile strength with the addition of P(3HB-ko-3HV). Thermal
analysis showed a decreasing in the melting point with the addition of PCL and P(3HB-co-
3HV). SEM micrograph showed the destruction occurred and erosion at surface of plastic film
during observation time. The rate of biodegradation showed that increasing of PCL and P (3HBco-
3HV) in a mixture of plastic film, so biodegradation increased.
Keywords: polystyrene, polycaprolactone, poly(3-hidroxybutyrate-co-3-hydroxyvalerate),
biodegradation, film plastic.
