摘      要：Bacterial Cellulose (BC) offers unique physical qualities such as high purity, crystallinity, and mechanical strength, as well as a high-water absorption capacity. Pineapple peel may be utilized as a source of cellulose, which is employed in a variety of applications. To improve the combination of BC and TiO2, TiO2 must be added, which affects the production of the cellulose membrane. The morphology of the membrane was studied using scanning electron microscopy (SEM). The membrane structure was studied using X-Ray Diffraction. SEM micrographs revealed that the control concentration increased the number of pores and had a small pore size of 81 nm, whereas the TiO2 concentration decreased the pore size. This drop is connected to the concentration increase. An XRD examination reveals the appearance of three peaks, the first at 14.12°, the second at 16.80°, and the third at 22.5°. The crystallinity index (Cl) and degree of crystallinity (Cr) increased with the addition of the specified concentration of TiO2, with the crystallinity index (CI) ranging from 66.8% to 76.1% and the degree of crystallinity (Cr) ranging from 50.3% to 68.6%.
