The study demonstrates that Caesalpinia sappan L. wood fiber provides good mechanical properties and biodegradability in polybutylene succinate composite films, showing potential as an environmentally friendly material.
Caesalpinia sappan L. wood fiber (CSWF), a novel advanced bio-reinforcement for polybutylene succinate (PBS) composite films, has shown significant promise ranging from 0 to 15 part per hundred of resin (phr). The functional groups and interactions, morphology, thermal stability, mechanical characteristics, and biodegradability were all investigated. Without treatment or any compatibilizers, CSWF could be well-dispersed in the PBS matrix. The PBS/CSWF10 composite film had highest mechanical strength, with a tensile strength of 12.21 N/mm(2) and a break elongation of 21.01%. Biodegradability studies indicated that the PBS/CSWF10 composite films degraded completely in three months. Furthermore, the E-a of degradation resulting from TGA and the shift of wavenumber resulting from FTIR revealed that the addition of CSWF has a greater interaction between additive and martix than conventional cellulose. The PBS/CSWF10 composite has the potential to be environmentally friendly, with promising short-term degradation and rising mechanical characteristics. Therefore, it is the optimum concentration of a certain biocomposite film. As a result, a novel advanced natural-based cellulose for biopolymer composites film was discovered, as well as other benefits for bio-reinforcement of the green plastic composite film industry.
