“…In Fig. 4(d), for ACOPNA-BMI, the typical bands at 1709 cm −1 and 830 cm −1 correspond to C_O vibrations of the imide and C_C vibrations of the bismaleimide, respectively, which indicates that copolymerization occurred between BMI and ACOPNA [30]. Fig.…”

The cured condensed polynuclear aromatic (COPNA) resin has excellent thermal stability and self-lubricating property which is popular for friction materials. However the cured resin has brittleness and poorly molding process due to its high cross-linking density. In this paper, the allyl-COPNA-BMI copolymer resin is prepared via a solution polymerization method, its structure, and its mechanical and tribological properties are investigated with FT-IR, SEM, TGA techniques. The copolymer anti-friction and anti-wear behaviors are tuned by varying the N,N'-4,4'-diphenylmethane-bismaleimide(BMI) monomer loading. The mechanical properties of the copolymer is the best when the BMI loading is 20 wt% upon these results. The tensile and impact strength of the copolymer/BMI 20 wt% is 12 MPa and 13.9 MPa, respectively. The lowest friction coefficient of copolymer/BMI 30wt% is 0.27, and its abrasion rate is 0.601510 -6 mm 3 /Nm. The initial thermal decomposition temperature of the copolymer/BMI 40wt% is 400 o C and 46.5 wt% of char residue ratio at 642 o C. The copolymer resins exhibit good thermal stability, abrasive resistance and mechanical properties compared to the pure COPNA.

Carbon dioxide, CO 2 , is thought to be a main culprit leading to global climate change and a wide variety of strategies have been proposed to reduce atmospheric CO 2 levels. Here, CO 2 is captured and subsequently electrochemically split into carbon materials in an electrolyzer comprising a eutectic mixture of carbonates, an Fe cathode and a Ni anode, at 600 C and current densities of 50, 100, 200 mA cm À2 . SEM, EDS, XRD and BET are employed to analyze the morphology, elemental composition, crystal structure as well as the BET surface area of the synthetic cathodic products. In addition, coulomb efficiency under different electrolytic conditions is measured via the comparison between moles of formed carbon product and the Faradays of charge passed during the electrolysis reaction. This paper investigated the effect of molten carbonate compositions on carbon product generation, and confirmed the visible dependence of produced carbon on the electrolytes.
