Abstract Thermal interface applications with biodegradable materials are one of the priority areas research. In this study, supernatant cellulose nano‐fibers (SCNF) were synthesized and optimized functionalized hexagonal boron nitride (h‐BN). The fabricated nanocomposite sheets SCNF h‐BN have been characterized for structural, chemical, physical, thermal stability, thermal, electrical transport properties. Different compositions samples performed, modified h‐BN: = 30:70 sample showed best results. contact angle 95.2° highlights hydrophobic properties nanocomposite, which makes it suitable moisture resistance applications. BN‐OH30/SCNF70 (modified 30:70) show an in‐plane conductivity 19.76 W/m·K out‐plane 0.96 W/m·K. Its resistivity exceeds 400 × 10 6 ohms·cm. composites low dielectric constants at high frequencies, making them ideal next‐generation electronics that require minimal energy losses along excellent frequency stability. increased resistance, heat properties, to SCNF, shows potential use
