Schematic illustration of clay and CNTs morphology in chitosan nanocomposites is shown in Figure 4.8. In the composites based on chitosan/CNTs containing 0.4 wt % CNTs, nanotubes can be well dispersed in chitosan, but no filler network could be formed due to its low concentration (Figure 4.8a). In the composites based on chitosan/clay containing 3 wt % clay, formation of 2D clay platelets network is possible (Figure 4.8b). In chitosan/clay-CNTs ternary nanocomposites, ID CNTs are confined in 2D clay platelets network, which results in a much jammed and conjugated 3D clay-CNTs network (Figure 4.8c). The interactions and networks in the system can be divided into (1) clay-clay network, (2) clay-CNTs network, (3) CNTs-polymer-clay bridging, (4) polymer-polymer network. The formation of different networks and interactions could be the main reason for the observed synergistic reinforcement of CNT and clay...
