【 摘 要 】

Summary. Composite materials polylactic acid/Reduced graphitic oxide (PLA/RGO) were prepared using the method of mixing chloroform solution. the chemical structure of chemically modified RGO obtained after reduction GO by infrared spectroscopy (FT-IR) was studied. PLA composites with different contents of RGO (1-3 wt%) in terms of distribution and morphology were compared, using optical microscopy. RGO better dispersion in the matrix of the PLA using chloroform as a solvent and 3% by weight of RGO was obtained.
