Preparation and characterization of the carbonized material of phenol–formaldehyde resin with addition of various organic substances

Synthesis of a hierarchical nanoporous carbon material with controllable pore size and effective surface area for high-performance electrochemical capacitors

“…40 Recently, polymer blend carbonization includes carbonizing composite polymers consisting of a carbon source and a resoluble polymer which is pyrolyzed to produce pores. 41,42 Porous carbons with different pore sizes were obtained by using the preparation approach. For example, the phase-separate of polymer blend for thermosetting polymer (carbon source) and thermoplastics polymer (pore-former) such as poly(vinyl butyral), 41 polyethylene oxide, 42 poly(methyl methacrylate), 43 polystyrene, 44 and polyethylene, 45 which were used to synthesize porous carbons by carbonizing the thermosetting polymers as well as pyrolyzing thermoplastic polymers.…”

Nevertheless, these polymer blends frequently happen to macro-phase separation in the carbonization process of thermosetting polymers, which is closely related to the inrm intermolecular interaction between thermosetting polymers (carbon source) and thermoplastic polymers (pore-former), resulting in as-obtained carbon materials with separate pore structure, diminutive pore volume, and small specic surface area.…”

Synthesis and characterization of carbon-coated LiNi1/3Co1/3Mn1/3O2 cathode material prepared by polyvinyl alcohol pyrolysis route

“…The pyrolysis of organic compound in inert atmosphere at higher temperatures (600-900 • C) is a commonly used carbon coating route [13,14]. This method, however, is difficult to be applied to * Corresponding author.…”

Co-treatment of novolac- and resole-type phenolic resins with coal-tar pitch for porous carbons

“…The resins are commonly used as a matrix precursor in carbon/ carbon composites [1] and as a binder in refractory materials [2]. The presence of ultramicroporosity in the resultant chars makes them promising raw materials for activated carbons [3][4][5][6], molecular sieving carbons [7,8], carbon membranes [9,10] and anodes in lithium-ion batteries [11].…”
