This work focuses on the preparation of cellulose-based biocomposites as a kind of potential leather-like alter-native. Herein, Kombucha-derived bacterial cellulose (KBC) cultured from black tea, waste and cane sugar was modified with different silanes (dimethyldichlorosilane, hexadecyltrimethoxysilane, vinyltriethoxysilane and 3-aminopropyltriethoxysilane) to incorporate hydrophobic property followed by mixing with polyurethane (PU) and polylactic acid (PLA). The improved hydrophobicity of KBC played a vital role in enhancing compatibility, homogenous mixing and providing a stable structure for the final products. The untreated and silane treated KBC/PU/PLA biocomposites were characterized for surface morphology, chemical structure, X-ray diffraction, thermal and mechanical stability as well biodegradation. According to results, the optimized biocomposites contained KBC 13.74% w/w, PU 73.89% w/w, and PLA 12.50% w/w compressed at 155 degrees C for 5 min. The prepared biocomposites possessed good elasticity, hydrophobic surface and moderate biodegradability. Basically, the fabricated materials urged possible responses for essential requirements of newly developed leather sub-stitutes with prospective application in fashion design industries like textile, footwear, bags, or interior covering products for the automotive industry.
