Dissolution Of Natural Fiber Using Ionic Liquid For Production Of Cellulose Nanoparticles

Natural fiber (NF) exhibits desirable properties such as renewability, biodegradability, environment-friendly, lightweight, low density, high specific mechanical performance, good electrical and thermal conductivities, and low cost. Cellulose nanoparticles (CNPs) embedded in NF possess even great...
