Afluffy ultrathin-wall mesoporous surface carbon foam (UMSCF) with high thermal conductivity wasprepared via carbon-thermal reduction reaction between a carbon foam and aluminium nitrate, and thenused as a supporting material for stearic acid (SA) to form shape-stabilized composite phase changematerials (PCMs). The UMSCF and the as-prepared SA/UMSCF composite PCMs were characterized bySEM, TEM, XRD, Raman, BET, FTIR, wettability test, compression test, TG, DSC, thermal cycling test andlaserflash method, respectively. Results shows that the carbon-thermal reduction temperature greatlyinfluences the microstructures of the UMSCF, and the UMSCF prepared at 1600 C (UMSCF-1600)possesses good lipophilicity, high thermal conductivity and superior mechanical properties. Theprepared UMSCF as supporting matrix simultaneously improves thermal conductivity and shapestabilizationof PCMs, as well as retains relative high phase change enthalpy. The melting and freezingenthalpy for SA/UMSCF-1600 composite was measured as 149.3 and 151.2 J/g, respectively. The thermalconductivity of the composite PCMs is as high as 1.725 W/m K, which increases by about 6.791-foldcompared with pristine SA. Meanwhile, the composites display good thermal reliability and chemicalstability, suggesting their promising characteristics for thermal management applications.

In this study, waste corrugated paper was used as carbon precursor with KOH-NaOH mixture (mole ratio was 51:49 and the melting point is 170 °C) as activator to prepare porous carbon at different reaction temperature and different mass ratio of KOH-NaOH mixture/waste corrugate paper fiber. The micro-morphology, pore structure information and composition of porous carbon were analyzed, and the formation mechanism of pores was investigated. The effect of activator amount and pyrolysis temperature on the morphology and structure of porous carbon were studied. The adsorption capacity of porous carbon was evaluated with the methylene blue as model pollutant. The effect of adsorbent amount, adsorption time and temperature on the adsorption performance of the porous carbon were analyzed. The maximum specific surface area is 1493.30 m2·g−1 and the maximum adsorption capacity of methylene blue is 518 mg·g−1. This study provides a new idea for efficient conversion and utilization of waste paper.
