Summary

As most of the biodegradable polymers find their origin in other alternate renewable sources, their use in the polymer composites technology is attractive; however, their use as an alternative to commercial nonbiodegradable polymers has emerged both as a goal and as a challenge. Bionanocomposites lead to improved performance of biopolymers at very low filler contents. A number of biopolymers such as polylactic acid (PLA), polycaprolactone (PCL), polyhydroxybutyrate‐co‐valerate (PHBV), and cellulose acetate have been reported in the literature to achieve reductions in the oxygen, water vapor, and carbon dioxide permeation by incorporation of fillers such as clay, nanofibers, and nanotubes. A number of factors including interfacial interactions, amount of filler, modification present on the surface of filler particles, humidity, processing conditions, and so on affect the barrier performance of the bionanocomposites.
