Investigation on thermal conductivity and physical properties of polythiophene/p-phenylenediamine-graphene oxide and polythiophene-co-poly(methyl methacrylate)/p-phenylenediamine graphene oxide composites

Retracted: A concise review on the elastomeric behavior of electroactive polymer materials

“…When there is no outside stimulant, the orientation range order of the mesogens compels the elastomer toward the direction of mesogens 50 . However, this sematic order is lost by the application of external electrical 51–53 or thermal stimulus 10, 36, 52–163 . The elastomeric backbone relaxes to its coiled confirmation (isotropic phase) by the application of thermal or electrical stimuli.…”

Epoxy-matrix polyaniline/p-phenylenediamine-functionalised graphene oxide coatings with dual anti-corrosion and anti-fouling performance

“… 55–57 The peaks at 1649, 1512 and 824 cm −1 can be attributed to the N–H, C C, and C–H, respectively, of a benzene ring with para -substitution. 58 …”

“…[55][56][57] The peaks at 1649, 1512 and 824 cm À1 can be attributed to the N-H, C]C, and C-H, respectively, of a benzene ring with para-substitution. 58 The FTIR spectrum of PANI is well-known to have peaks at 1106, 1249, 1480, and 1563 cm À1 . 59 The absorption peaks related to the benzene and quinone rings appear at 1480 and 1563 cm À1 , respectively.…”

Preparation of p-Phenylenediamine Modified Graphene Foam/Polyaniline@Epoxy Composite with Superior Thermal and EMI Shielding Performance

“…Notably, with the further in-situ polymerization of PANI, the κ of GF/PANI 5:1 @EP and GF/PANI 4:1 @EP is further improved to 0.436 W m −1 K −1 and 0.622 W m −1 K −1 , respectively. Because the graphene sheets have been connected by the presence of PANI during the in-situ polymerization process forming a continuous network for phonon transportation pathway to improve the thermal properties [ 23 ]. However, with the overload of PANI to 33% (GF/PANI 3:1 @EP), the κ displays a dramatic decrease to 0.466 W m −1 K −1 due to the entanglement and the agglomeration of excessive PANI in the composites.…”

“…Wang et al reported the modification of GO by octadecylamine (ODA) to deliver modified graphene oxide/styrene butadiene rubber (GO-ODA/SBR) composites with higher tensile strength and elongation at break due to the covalent crosslink of GO sheets [ 22 ]. The p-phenylenediamine (PPD) was also applied to modify the GO filler, with an enhancement in κ to 1.42 W m −1 K −1 with only 1.5 wt% of filler loading [ 23 ].…”
