Polymer matrix composites, filled dispersion method

In 2012, G. H. Kim et al. prepared Gp-filled PEDOT PSS composite films via solution spin coating method [3]. XPS and Raman analyses identified that strong tt-tt interactions existed between Gp and PEDOT PSS, which facilitated the dispersion of Gp in the polymer matrix and reduced the carrier hopping barrier. The uniformly distributed Gp increased the interfacial area by 2-10 times as compared with CNT based composite on the same weight percentage. Moreover, well-stacked multilayer structure... 

Micron-sized fillers, such as glass fibers, carbonfibers, carbon black, talc, and micronsized silica particles have been considered as conventional fillers. Polymer composites filled with conventional fillers have been widely investigated by both academic and industrial researchers. A wide spectrum of archival reports is available on how these fillers impact the properties. As expected, various fundamental issues of interest to nanocomposites research, such as the state of filler dispersion, filler-matrix interactions, and processing methods, have already been widely analyzed and documented in the context of conventional composites, especially those of carbon black and silica-filled rubber compounds [16], It is worth mentioning that carbon black (CB) could not be considered as a nanofiller. There appears to be a general tendency in contemporary literature to designate CB as a nanofiller - apparently derived from... 

Polymer nanocomposites (i.e. the composites consisting of polymer matrix filled with nanosize particles) are especially interesting due to their high longtime stability (polymer matrix prevents both oxidation and coalescence), distinguishing them from thin solid films and free high-dispersion particles. They also have relatively simple synthesis methods.
