摘要
Cellulose, a major proportion of all plant resources are not utilized at its best. Hence, this investigation explores the potential of cellulose fraction in bark fibers of Thespesia populnea for real time use by evaluating its anatomical, physicochemical, mechanical, thermal and morphological properties. Anatomical studies confirm two types of phloem fiber cells based on dimensions of secondary cell wall and lumen. Significant concentration of cellulose (70.12%) helps to attain favorable outcomes in tensile strength (557.82 ± 56.29 MPa). FTIR spectra confirm the presence of cellulosic compound in fiber structure and the size of crystalline cellulose is estimated as 35.76 Å using XRD results. Thermal profile of TGA and DSC validates that fiber is steady up to 245.4 °C and cellulose degradation befalling between 250 °C and 370 °C accounts for major weight loss in fiber. Images acquired through SEM and AFM depict that the fiber surface is smooth with average roughness of 3.002 nm.
