Organic-inorganic hybrid epoxy layered silicate/CNT nanocomposites

The main aim of the work was the development of hybrid matrix materials and nano hybrid composites based on industrially valuable polymeric intermediates viz., epoxy resin, functionally terminated siloxane and bismaleimides and their characterized by different methods. As nanostructured hybrid organic-inorganic composites have attracted considerable attention recently, both from the perspectives of fundamental research and their technological applications. The hybrid bismaleimide modified siloxane-epoxy matrix systems were developed using hydroxyl-terminated polydimethylsiloxane (HTPDMS) and Synthesized bismaleimides namely N,N-bis(maleimido) 4,4-diphenylmethane, 1,1-bis(4-maleimido)cyclohexane and 10-phenyl, phenonoxaphosphine-3,8-di (2-hydroxy-3-(p-maleimidobenzoyloxy) propyl) ester-10-oxide which were used as chemical modifiers for epoxy resin. Synthesized tetraglycidyl diamino diphenyl methane and bismaleimides along with preparation of hydroxyl-terminated poly dimethyl siloxane modified epoxy, bismaleimides modified epoxy, bismaleimides modified HTPDMS epoxy blends were prepared using diamino diphenyl Sulphone as a curing agent and characterized by FTIR, DSC, TGA studies.
