Synthetic chiral helical polymers have achieved impressive progress in past few decades. Unfortunately, how to construct chiral helical polymer‐derived functional materials still remains highly challenging. The present contribution reports an unprecedented, one‐step strategy for judiciously combining chiral helical polymer with graphene to construct chiral hybrid foams. Graphene oxide (GO), ascorbic acid (L‐AA), Rh catalyst, and an achiral acetylenic monomer bearing phenylboronic acid group are mixed in an aqueous dispersion. Under mild conditions, the monomer underwent polymerization; meanwhile GO transforms into reduced graphene oxide (RGO) which in situ self‐assembles to construct a 3D porous structure. Herein, L‐AA simultaneously plays double roles: 1) working as a chiral source for the monomer to undergo helix‐sense‐selective polymerization or transferring its chirality to the polymer chains via forming borate structure; and 2) working as a reducing agent for reducing GO. The preparation strategy combines four processes into one single step: monomer polymerization, chirality transfer, reduction of GO, and RGO's self‐assembly. The eventually obtained chiral hybrid foams demonstrate advantages of porous structure, chirality, and reversible borate functional groups. The established preparation strategy promises a potent platform for conveniently constructing advanced chiral polymeric materials and even chiral hybrids starting from achiral monomers.

“…Graphene nanosheet (GN), as a kind of carbon-based material, is a 2D nano-filler with single-layer atoms packed in a hexagonal lattice, 3,4 which has aroused great interest and broadened its potential applications in particular fields such as composite reinforcement, 5 supercapacitors, field-effect transistors, energy devices, sensors and lubricants [6][7][8][9] owing to its distinctive properties, such as superior thermal and electrical conductivity, [10][11][12][13][14] excellent mechanical strength and flexibility [15][16][17] and large specific surface area. 18,19 Plenty of research has been dedicated to various polymer/GN composites, [20][21][22][23] but research on PEI/GN composite foams has rarely been reported.…”

“…18,19 Plenty of research has been dedicated to various polymer/GN composites, [20][21][22][23] but research on PEI/GN composite foams has rarely been reported. Ling et al 1 reported a kind of PEI/GN composite foam for electromagnetic interference shielding and found that electromagnetic interference shielding increased from 17 to 44 dB g -1 cm 3 , and a tensile strength as high as ca 8 MPa was achieved. Abbasi et al 24 prepared PEI/GN foam through the method of water-vapor-induced phase separation (WVIPS) and observed that all foams presented a homogeneous cellular morphology.…”

Based on the industrialized reduced graphene oxide (RGO) product, polyetherimide (PEI)/RGO composite foam was prepared by a water‐vapor‐induced phase separation process by incorporation of polysiloxane (SI) as a compatibilizer. It was found that PEI/SI molecules were intercalated into the RGO layers through strong interfacial interaction and RGO with increased layer thickness was uniformly distributed in the PEI matrix. The composite foam possessed a homogeneous spherical‐like cell structure with narrow cell size distribution and low apparent density. In the range of 0–1 wt% RGO‐SI content, the area under the stress–strain curves increased dramatically, indicating the significantly increased toughness of the composite foam, while the tensile strength reached a maximum of 14.5 MPa at 1 wt% RGO‐SI as a result of the reinforcing effect of RGO‐SI on the foam. The addition of RGO‐SI led to a remarkable increase in Tg. Compared with neat PEI foam, the thermal degradation temperature and char yield of the composite foam clearly increased, while in the range of 0.5–3 wt% RGO‐SI a high storage modulus was maintained at high temperature, reaching about 300 MPa at 200 °C, indicating a remarkable improvement of the thermal mechanical stability of the foam. © 2018 Society of Chemical Industry

“…The non‐uniform distribution of graphene can be attributed to its high theoretical surface area (2,630 m 2 /g), high aspect ratio (1272) , and strong intermolecular π – π attractive forces . The limitation has consequently prompted the need for 3D form of graphene in polymer composites .…”

An electrostatic spraying technique was used to synthesize 3D graphene foam (GrF)‐reinforced polyurethane (PU) composites. Glass transition temperature (Tg) of PU increased from 120 to 148 °C after 3.3 vol% GrF addition. Strong interfacial bonding accounts for the improvement in Tg of PU‐GrF composites. Energy dissipation behavior is probed at multiple load scales to examine the intrinsic and structural damping characteristic. Micro‐scale damping at 1 mN and 1,000 Hz exhibited loss tangent value (tan δ), which is 200% higher and 3 times faster than PU. Nano dynamic mechanical analysis of PU‐3.3 vol% GrF composite demonstrated up to 383% tan δ improvement than of PU at 5 μN dynamic load. Physical mechanisms including rippling effect and weak van der Waals forces in graphene account for the high energy dissipation of PU‐GrF composite. This study suggests that PU‐GrF nanocomposites have the potential to serve as a good damping material in vibrating systems. POLYM. COMPOS., 40:E1862–E1870, 2019. © 2018 Society of Plastics Engineers
