Synergistic toughening of epoxy resin byCTBNandCM‐β‐CD

Carboxymethyl‐β‐cyclodextrin (CM‐β‐CD) and carboxyl terminated liquid nitrile rubber (CTBN) were used as binary component fillers in toughening the epoxy resin (E‐54). For a single component filler system, the addition of CTBN resulted in significantly improved fracture toughness but reduction of glass transition temperature ( T g ) and modulus of epoxy resin. On the other hand, the addition of CM‐β‐CD resulted in a modest increase in modulus...
