Morphology in Organic–Inorganic Composites

摘要: Polymeric materials are generally reinforced with inorganic fillers in order to reduce cost or enhance mechanical, thermal, rheological and barrier properties. The used have different geometrical dimensions thus affect the polymer properties differently. For example, silica (and calcium carbonate) particles spherical (aspect ratio near 1) strength of polymeric materials. On other hand, clay graphene platy nature electrical polymers. Fibers nanotubes highest aspect longitudinal as well Most common factor affecting filler performance is dispersion distribution matrix. Good mandatory achieve efficient interface between organic components. Various microscopy techniques constitute most powerful methods characterize morphology organic–inorganic described by diverse examples presented following sections. characterization nanocomposites also poses additional challenges owing large number nano-sized particles. microscopic acts a quality control tool poorly dispersed systems can be improved changing process parameters. Apart from particles, provide information on alignment fibrous
