Synthesis and characterization of pan nanofiber reinforced with functionalized mixture CNT/CNF by electrospinning technique

In this study, functionalization of CNT and CNF was done using oxidative acid treatment with concentrated HCl and HN03 solution mixture at 3: 1 ratio. Various process variables such as duration, mode of treatment, agitation and temperature are controlled, and consequently the functional groups gr...
