Biomass based Polylactide (PLA) has been received attention because of its potential to replace the petroleum based polymer. However, poor melt strength, mechanical properties, and brittleness of the PLA have delayed its commercialization in a broader range of industries. Carboxymethyl cellulose (CMC) is non-toxic biomaterial which has been used as medical applications, viscosity modifier, hydrogels, and adhesives. The CMC was mixed with PLA matrix by twin screw extruder and expected to play a role as adhesive and reinforcement. The PLA/CMC composites prepared by melt processing can be promising way to increase the brittleness and mechanical properties of the PLA. In this research, flexural modulus, mechanical properties, melt stability, thermal properties, rheological properties and morphology was investigated. This research was supported by the Ministry of Science, ICT and Future Planning of Korea; Project No. NRF-2015M3C8A6A06014792. |
