Rheology of Organoclay Nanocomposites Based on Thermoplastic Polymer

1 Rheology of Organoclay Nanocomposites Based on Thermoplastic Polymer 

There are so many thermoplastic polymers that it is not possible to present the rheological behavior of organoclay nanocomposites based on each of them. Here, we will consider rheological behavior of organoclay nanocomposites based on polycarbonate (PC), which can be regarded as being representative of the majority organoclay 

The smaller the size of particulates (thus the larger the surface area of particulates) in a nanocomposite, the lower will be the concentration of the particulates that may give rise to yield behavior. Note that little or no attractive interactions exist between PC and the surface of MMT in the 95.7/4.3 PC/MMT nanocomposite. 

Block copolymers have an advantage over flexible homopolymers in introducing functional groups. Thus, block copolymers are very attractive for use in nanocomposites.
