Abstract
Cellulose was dissolved in an environment friendly aq.(7%NaOH/12% urea) solvent that was precooled to -12 oC. Turmeric powder was added in different proportions and the composite films were cast on glass plates and regenerated in dilute sulfuric acid bath. The films were uniform and transparent of yellow color. The effect of turmeric powder loading on the tensile, optical, thermal degradation and cell viability was studied. The tensile properties, optical transparency and cell viability were found to be higher for the composite films. The films were thermally stable up to 350 oC.
