NANOCLAY BASED POLYMER COMPOSITES & THEIR CHARACTERIZATION TECHNIQUES. This book provides a detailed insight on survey of nanoclay and organomodified nanoclay as nanofillers in polymeric resins, organomodification of naturally available Na-IB nanoclay using cationic surfactants having long chain alkyl ammonium at two CEC. The modification process parameters such as time, speed, temperature and duration of ball milling were considered for the ion exchange process. Modification of Na-IB using HDTMA-Br, TPP-Br and TBA-Br considering the influence of modification parameters such as speed, duration of centrifuging for surfactant mixing, oven temperature for drying, speed and duration of ball milling for refining the modified nanoclay and Materials, Processes and Testing of nanoclay dispersed polymers. Characterizations techniques of nanoclay and organomodified nanoclay using XRD, SEM, FTIR, CHNS, EDAX, ZPA, TGA and characterizations techniques for polymer nanocomposites were also discussed.
