“…The good thermal stability resembles thioether polymer so that the residues are likely crosslinked sulfur-containing substrate with a thioether structure derived from the capping groups. [32] Owing to this crosslinking reaction, sulfur atoms in SOPS cannot completely vanish and therefore the n value derivation from TGA is lower than that of EA.…”

Organic polysulfides are linear sulfur chains (R-S n-R, n ≥ 2) capped with organic moieties, and are appealing cathode materials in lithium batteries. The theoretical capacity of polysulfides essentially relies on the length of the sulfur chains; long-chain polysulfides could store more charges than short-chain polysulfides. Herein, we report the successful synthesis of a long-chain solid organic polysulfide (SOPS) by a radical coupling method and disclose 1 Main equal contribution.

In this study, we present a facile method of fabricating graphene oxide (GO) films on the surface of polyimide (PI) via layer-by-layer (LBL) assembly of charged GO. The positively charged amino-phenyl functionalized GO (APGO) is alternatively complexed with the negatively charged GO through an electrostatic LBL assembly process. Furthermore, we investigated the water vapor transmission rate and oxygen transmission rate of the prepared (reduced GO [rGO]/rAPGO) 10 deposited PI film (rGO/rAPGO/PI) and pure PI film. The water vapor transmission rate of the GO and APGO-coated PI composite film was increased due to the intrinsically hydrophilic property of the charged composite films. However, the oxygen transmission rate was decreased from 220 to 78 cm 3 /m 2 ·day·atm, due to the barrier effect of the graphene films on the PI surface. Since the proposed method allows for large-scale production of graphene films, it is considered to have potential for utilization in various applications.

“…The functional groups on SrGO (thiol, thioether, sulfoxide, sulfonic acid, and sulfone) can be the starting point of polymerization, considering the nucleophilic aromatic substitution (SNAr) mechanism of PPS polymerization [33][34][35][36][37]. PPS grafting from these functional groups would provide (i) enhanced dispersibility through the interaction between PPS from the matrix and composites, resulting in enhanced thermal and electrical conductivities of SrGO and the matrix [38][39][40][41], and (ii) the effective load transfer between the matrix and SrGO nanosheets, resulting in an enhanced mechanical strength [14,42,43]. Therefore, as a potential application, masterbatch (MB) of SrGO could afford a homogeneous polymer because it is well-dispersed in the polymer matrix during the melt mixing process.…”

The sulfur on the sulfur-assisted reduced graphene oxide (SrGO) surface provides the origin of poly(phenylene sulfide) PPS-grafting via SNAr mechanism. In-situ polymerization from sulfur on SrGO afforded surface modification of SrGO, resulting in enhanced dispersibility in PPS. The tensile strength, electrical and thermal conductivities, and flame retardancy of PPS-coated SrGO were efficiently enhanced using highly concentrated SrGO and masterbatch (MB) for industrial purposes. Three-dimensional X-ray microtomography scanning revealed that diluting MB in the PPS resin afforded finely distributed SrGO across the PPS resin, compared to the aggregated state of graphene oxide. For the samples after dilution, the thermal conductivity and flame retardancy of PPS/SrGO are preserved and typically enhanced by up to 20%. The proposed PPS/SrGO MB shows potential application as an additive for reinforced PPS due to the ease of addition during the extrusion process.
