Abstract

Polystyrene (PS) is one form of the plastic that is most widely utilized for household application. However, plastics made from PS can pollute the environment. Hence, it is necessary to modify PS by mixing it with a biodegradable polymer like poly (ɛ-caprolactone) (PCL). The focus of this research was to determine the mechanical and thermal properties of PS/PCL polyblends. In this research, polyblend are prepared by mixing PS with PCL that acquired using the bis(dibenzoylmethanato)zirconium(IV) chloride bis(dibzm)2Zr catalyst. The method employed is solvent casting with a ratio of PS/PCL of 10/0, 10/1, 10/2, 10/3, and 10/4 (w/w). The optimum mechanical properties were obtained in 10/2 mixing which had a tensile strength of 6.72 MPa with 1.01% in elongation. Furthermore, the optimum PS/PCL polyblend was also characterized using DSC to determine its thermal properties.

Abstract

Although polystyrene (PS) finds widespread use in household applications, its non-biodegradable nature raises concerns about its environmental impact. Therefore, modifying PS by blending it with a biodegradable polymer such as poly(ɛ-caprolactone) (PCL) is essential. This study focuses on investigating the functional groups and structural characteristics of PS/PCL blends. In this study, we produce polyblend using the solvent casting method. On the other hand, the PCL employed in this study was synthesized using the bis(dibenzoylmethanato)zirconium(IV)chloride (bis(dibzm)2Zr) catalyst. Next, the FTIR analysis indicates a Van Der Wall’s interaction between PS and PCL. Therefore, we did not find any absorption of new functional groups outside of the PS and PCL functional groups. Next, the XRD analysis revealed that polyblend has a more crystalline structure than PS. Meanwhile, PCL has a more crystalline structure than PS/PCL polyblend and pure PS.

Abstract

Polystyrene (PS) is one form of the plastic that is most widely utilized for household application. However, plastics made from PS can pollute the environment. Hence, it is necessary to modify PS by mixing it with a biodegradable polymer like poly (É›-caprolactone) (PCL). The focus of this research was to determine the mechanical and thermal properties of PS/PCL polyblends. In this research, polyblend are prepared by mixing PS with PCL that acquired using the bis(dibenzoylmethanato)zirconium(IV) chloride bis(dibzm)2Zr catalyst. The method employed is solvent casting with a ratio of PS/PCL of 10/0, 10/1, 10/2, 10/3, and 10/4 (w/w). The optimum mechanical properties were obtained in 10/2 mixing which had a tensile strength of 6.72 MPa with 1.01% in elongation.
