Gum ghatti based novel electrically conductive biomaterials: A study of conductivity and surface morphology

“…Gg-cl-poly(AAm-ipn-aniline)-HCl 0.80·10 -7 Gg-cl-poly(AAm-ipn-aniline)-HClO 4 0.50·10 -6 Gg-cl-poly(AAm-ipn-aniline)-HNO 3 0.10·10 -8 Gg-cl-poly(AAm-ipn-aniline)-pTS 0.20·10 -7 However, Gg-cl-poly(AAm) showed peaks at 22 and 35.4° with relative intensities of 289 and 150, respectively. It is interesting to note that the intensity of the diffraction peaks increased with a cross linked network on moving from Gg-cl-poly (AAm) to Gg-cl-poly (AAm-ipn-aniline), which indicated the enhancement in crystallinity [30,44]. This enhancement in crystallinity could be attributed to the interaction of PANI chains in the crosslinked network of Gg-cl-poly(AAm) [54].…”

“…The gum ghatti showed broad peaks at 3434 and 1032 cm -1 , characteristics of the saccharide structure (due to -OH stretching) [44]. The peaks at 2925 and 1622 cm -1 was assigned to the stretching vibration of the -CH group and -C=O stretching of a carbonyl group respectively [30].…”

“…TGA of G g showed two-stage decomposition. G g exhibited initial decomposition temperature (IDT) at 207°C and final decomposition temperature (FDT) at 534°C [44]. Whereas, Gg-cl-poly(AAm) showed IDT at 190°C and FDT was at 578°C.…”

Study of ionic charge dependent salt resistant swelling behavior and removal of colloidal particles using reduced gum rosin-poly(acrylamide)-based green flocculant

“…1b that initially P s increased with increase in time interval and showed maximum P s (350 %) at 120 min. Further increase in time interval resulted in lower grafting, which might be due to the predominance of homopolymerization [29,31].…”

“…XRD results clearly indicated that amorphous gum rosin acids were transformed into a crystalline entity on reduction to gum rosin alcohols and on grafting with acrylamide resulted in a semi-crystalline material. This could be attributed to the incorporation of poly(AAm) chains which disrupted the crystalline lattice [14,31].…”
