Natural fiber-reinforced nanocomposites (NFRCs) are proved as the best alternative for synthetic composites in view of cost and environmental effects. NFRCs have been produced from agro-waste such banana tree fiber (BFs), because BF strong, light-weight, smaller elongation. To improve quality BF, multiwall carbon nanotubes (MWCNTs) used reinforcing filler. MWCNTs functionalized by an ecofriendl...
