Abstract:
Poly(lactic-acid) (PLA), a bio based polymer, was modified with microfibrillated cellulose and lignocellulose fibres. The film casted composites were compared to each other in terms of dispersion and mechanical properties. Through the hydrophobic nature of the lignin, these lignocellulose specimens exceeded the other composite specimens in their properties. Subsequent, PLA with the lignocellulosic and cellulosic fibres were compounded and composed to a Filament, with an extruder. After this extrusion process, the filaments were tested and interestingly, the results from the casted composite films could not be repeated. The different influencing factors of these processes and possible solutions to enhance the miscibility from PLA to cellulosic material were discussed.
