ABSTRACT
The nanocomposite of diglycidyl ether of bisphenol-A and diglycidyl ether of bisphenol-A/tetrabromobisphenol-A blend with purified multiwalled carbon nanotube and acid-functional multiwalled carbon nanotube were processed by solution route. According to field emission scanning electron microscope, diglycidyl ether of bisphenol-A/purified multiwalled carbon nanotube depicted poor dispersion and aggregated morphology, however, diglycidyl ether of bisphenol-A/acid-functionalized multiwalled carbon nanotube revealed better dispersion in matrix. The diglycidyl ether of bisphenol-A/tetrabromobisphenol-A/purified multiwalled carbon nanotube had higher thermal stability as T0 of 369°C and Tmax of 569°C were observed. Nonflammability of diglycidyl ether of bisphenol-A/tetrabromobisphenol-A blend-based material was 44%, i.e., higher than diglycidyl ether of bisphenol-A/purified multiwalled carbon nanotube series. Diglycidyl ether of bisphenol-A/tetrabromobisphenol-A/purified multiwalled carbon nanotube 0.1 had crystalline morphology with diffractions at 12.77° and 26.8°. The diglycidyl ether of bisphenol-A/tetrabromobisphenol-A/multiwalled carbon nanotube nanocomposite revealed electromagnetic interference shielding effectiveness of ∼12.1 dB, i.e., desired for aerospace applications.
