Název v původním jazyce

Reinforcement of enzyme hydrolyzed longer jute microcrystals in polylactic acid

Popis výsledku v původním jazyce

The waste jute fibers generated in textile industries were hydrolyzed to the form of longer jute microcrystals of size 5423, 3789, and 2,035 nm diameter after 4, 6, and 8 days of cellulase enzyme treatment. The obtained crystals were incorporated into poly(lactic acid) matrix at 1, 5, and 10 wt% loading to prepare composite films by solvent casting. The reinforcement potentials of microcrystals were investigated from the improvements in mechanical properties based on tensile tests, dynamic mechanical analysis, and differential scanning calorimetry. The maximum improvement was observed in case of 1 wt% composite film where tensile strength increased by 39.72% and crystallinity increased by 57.43% over neat PLA film. From storage modulus results, the improvement in load bearing capacity of composite films was found negative at 60°C than 35°C, which showed failure of jute microcrystals to improve the softening temperature of PLA matrix. At the end, when experimental results of initial modulus were compared with predicted values obtained from different mechanical models, a good level of agreement was found at 1 wt% loading of JMC.
