الملخص EN
Crystalline cellulose was extracted from jute by hydrolysis with 40% H2SO4 to get mixture of micro/nanocrystals.
Scanning electron microscope (SEM) showed the microcrystalline structure of cellulose and XRD indicated the Iβ polymorph of cellulose.
Biodegradable composites were prepared using crystalline cellulose (CC) of jute as the reinforcement (3–15%) and poly(lactic acid) (PLA) as a matrix by extrusion and hot press method.
CC was cellulose derived from mercerized and bleached jute fiber by acid hydrolysis to remove the amorphous regions.
FT-IR studies showed hydrogen bonding between the CC and the PLA matrix.
The X-ray diffraction (XRD) and differential scanning calorimetry (DSC) studies showed that the percentage crystallinity of PLA in composites was found to be higher than that of neat PLA as a result of the nucleating ability of the crystalline cellulose.
Furthermore, Vicker hardness and yield strength were found to increase with increasing cellulose content in the composite.
The SEM images of the fracture surfaces of the composites were indicative of poor adhesion between the CC and the PLA matrix.
The composite with 15% CC showed antibacterial effect though pure films but had no antimicrobial effect; on the other hand its cytotoxicity in biological medium was found to be medium which might be suitable for its potential biomedical applications.
