Effect of Wood Flour on Structural and Thermal …

Abstract: Poly (lactic acid) (PLA) were compounded with wood flour and triclosan. The wood/PLA composites were then characterized using differential scanning calorimeter (DSC) and the antibacterial activity was also assessed via plate count agar (PCA) under a wide range of contact times using Escherichia coli (E.coli) as the testing bacteria.
