Nanokomposit berbasis nanokarbon berpotensi menghasilkan produk yang lebih inovatif dan unggul. Carbon Nanotube (CNT) merupakan salah satu nanokarbon berstruktur selimut heksagonal karbon dan berbentuk tubular dengan susunan atom karbon paralel dengan arah tubularnya. Keunggulan karakteristik intrinsik dari CNT melahirkan karakteristik unik seperti sifat elektronik, optik, dan magnetik yang tidak ditemukan di nanoselulosa. CNT berukuran 1–100 nm tidak dapat berdiri sendiri sehingga pengembangan nanokomposit menjadi penting dilakukan untuk menghasilkan material dengan sifat baru. Berdasarkan latar belakang permasalahan lingkungan dan energi, serta potensi nanoselulosa dan nanokarbon, pada naskah orasi ini disampaikan pemanfaatan nanokomposit berbasis nanoselulosa dan nanokarbon sebagai material fungsional. Bioselulosa mempunyai potensi besar sebagai kemasan yang ramah lingkungan untuk mengatasi permasalahan sampah plastik yang tidak dapat didegradasi secara alami. Sementara itu, nanokomposit CNT merupakan material fotokatalis dan support elektrokatalis yang dapat digunakan sebagai pengganti carbon black pada sel bahan bakar berbasis polimer. Naskah orasi ini memaparkan perkembangan iptek dan potensi nanoselulosa dan nanokarbon, pengembangan nanokomposit berbasis nanoselulosa dan nanokarbon, serta peluang pemanfaatan nanoselulosa dan nanokarbon di Indonesia, yang akan disampaikan pada Bab II–IV.
