Great enhancement of mechanical features in <scp>PLA</scp> based composites containing aligned few layer graphene ( <scp>FLG</scp> ), the effect of <scp>FLG</scp> loading, size, and dispersion on mechanical and thermal properties

Four series of polylactide (PLA) based composite films containing horizontally aligned few layer graphene (FLG) flakes high aspect ratio and adsorbed albumin are prepared. The mechanical thermal properties varies with percentage, dispersion degree size FLG flakes. Great improvement up to 290% 360% tensile modulus strength respectively were obtained for the lateral at 0.17% wt, 60% 80% very well dispersed 0.02% wt FLG. composites PLA PEG-PLLA 0.07% ductile showing enhancement elongation break 88%. Relatively electrical conductivity, 5 × 10−3 S/cm, is measured film charged 3%
