Effect of in-situ oxidative preparation on electrical properties of Epoxy/PANi/MWCNTs nanocomposites

Abstract

Conductive adhesives based on Epoxy/Polyaniline/MWCNT (EPM) system doped with Paratoluensulfonic acid (p-TSA) have been successfully synthesis via different methods and characterized. The composites were prepared by in situ synthesis of aniline/MWCNTs within epoxy matrix and direct physical mixing. X-ray diffraction (XRD) spectrum established the existence of MWCNT in the structure and showed that the morphology of samples was amorphous. FT-IR results confirmed that the composites were successfully synthesis and there is strong coupling between the PANi and MWCNT. The microstructure of the conductive adhesives was considered by field emission scanning electron microscopy. The in situ technique contributes for the development of a conducting path with lower amount of PANi/p-TSA. Electrical properties as a function of PANi and MWCNTs contents have also indicated a great interaction between polyaniline, MWCNT and epoxy matrix by in situ polymerization procedure.

Bio‐based epoxy/polyaniline nanofiber‐carbon dot nanocomposites as advanced anticorrosive materials

“…also reported nanocomposites with polyaniline/magnetite epoxy nanocomposites where the elongation was about 9% and, therefore, these nanocomposites are highly brittle in nature, which may be due to aggregation of the nanoparticles in the matrix. Thus, the elongation (%) was found to be far better in the present study compared to the earlier reported data . This is due to the sliding of the graphitic layers of CD and the polymeric chains of PN in the PC nanohybrid under stress, which contributes to the improvement in the elongation and flexibility of the EPCI nanocomposites .…”

“…On the other hand, the increasing trend in adsorption at 2958 cm −1 [22] can be clarified with more involvement of silane coupling agents with raising the BO content. Carbonyl groups C=O are kept constant during reactions since they do not participate in the chemical fluctuations and as verified from the peak at 1731 cm −1 in all samples [23]. The fixed position of the carbonyl group results from the absence of ionic bonding between boehmite hydroxyl groups and polymer functional groups [24].…”

Fabrication of renewable resource based hyperbranched epoxy nanocomposites with MWCNT-polyaniline nanofiber-carbon dot nanohybrid as tough anticorrosive materials

“…However, the flexibility of these nanocomposites is very low and therefore, their applications are limited. On the other hand, Imani et al [27] prepared epoxy nanocomposites by incorporating PANi/MWCNT doped with para-toluene sulfonic acid (p-TSA). The nanocomposites showed improved electrical conductivity which is appropriately utilized for conducting adhesive application.…”
