Abstract
The chapter reviews current research trends on polymer/layered silicate nanocomposites (PLSNCs) materials, including strategies for fabrication of the PLSNCs possessing discrete dispersion of the nanofillers. PLSNCs and their self-assembly behavior have been approached to produce nanoscale polymeric materials. Additionally, these nanocomposites have been proposed as model systems to examine polymer structure and dynamics in confined environments. The chapter highlights the mesostructure development in PLSNC melts with the primary focus on flow behavior and an analogy to soft glassy dynamics. In characterizing layered silicate including layered titanate (HTO), the surface charge density is particularly important because it determines the interlayer structure of intercalants as well as cation-exchange capacity (CEC). There are several factors that play important roles in producing exfoliated nanocomposites: chemical affinity between the surface of organically modified layered nanofillers (OMLFs) and polymer matrix, melt viscosity of the polymer matrix, and capillary pressure drop within the nanogalleries.
