MANUFACTURE OF PLASTICS FILM CONTAINING OF POLYSTIRENE, POLYCAPROLACTONE, POLY(3-HIDROKSIBUTYRATE-CO-3-HIDROXYVALERATE) AND BIODEGRADATION STUDY IN OCEAN WATER
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 (3HB-co-3HV)
in a mixture of plastic film, so biodegradation increased.
