چکیده انگلیسی
The transcendent mechanical properties of carbon nanotube (CNT) hold the promise of delivering contributory reinforcing effect in soft polymeric materials. But, the built-in-risk of the environmental susceptibility of the CNT/polymer interface should be well explored before certifying it for a particular application. Present investigation reports the reinforcement efficiency of CNT in epoxy as a function of environmental temperature. Nanocomposite with 0.2% CNT, which shows maximum strength and modulus at room temperature, exhibits the poorest strength and modulus at 90 °C. Dynamic mechanical thermal analysis (DMTA) has also been carried out to study the variation of thermomechanical properties of nanocomposites with temperature. A decrement in the glass transition temperature (Tg) of the polymer was obtained due to CNT reinforcement upto 0.2%. Post-failure fracture surface analysis was done to underneath the dominating strengthening, toughening and weakening mechanisms.
