Mechanical and Electrical Properties of CNT/Natural Biopolymer Composites
Table 7.2 represents mechanical and electrical information of CNTs/natural polymer
compared with neat natural polymer. These investigations show the higher mechanical
and electrical properties of CNTs/natural polymers than neat natural polymers.
