Surface modification of montmorillonite (MMT) was done to improve the basal spacing using a column chromatography technique with quaternary long chain ammonium salt as an intercalent. An increase in d-spacing of organically modified montmorillonite (OMMT) was confirmed by X-ray diffraction and found to increase from 16 to 22 Å. The d-spacing was maximal (22 Å) due to ion exchange column of sufficient...
Poly(lactic acid) (PLA) was synthesized using condensation polymerization of L-lactic acid using a controlled ultrasonic cavitation technique. Polystyrene (PS) was used to prepare the PS:PLA and PS:PLA:organically modified montmorillonite (OMMT) composites. PS was dissolved in benzene (10:90) and kept overnight for dissolution. Meanwhile, surface modification of montmorillonite was done using a column...
