Biodegradable polymer nanocomposite and method for production thereof |
| abstract |
A method of producing a biodegradable polymer nanocomposite comprises dispersing graphene nanoplatelets into a biodegradable polymer and extruding the resulting composition. The graphene nanoplatelets may be functionalised graphene, doped graphene, graphene oxide, or reduced graphene oxide. The biodegradable polymer may be a natural or synthetic polymer, such as polylactic acid (PLA) or a polyhydroxyalkanoate (PHA). The extrusion may be performed using a single or multiple screw and barrel extruder at a temperature of 120-160ºC. Typically, shear developed between screws or between screw and barrel is sufficient to deagglomerate agglomerated graphene nanoplatelets. The method may also comprise a step in which the biodegradable polymer is extruded prior to dispersing the graphene nanoplatelets. A biodegradable polymer nanocomposite is also disclosed, which comprises unagglomerated graphene nanoplatelets dispersed in a biodegradable polymer. |
