In this work, we synthesized p-phenylenedi- amine modified carbon nanotubes (P-CNTs) by diazotiza- tion reaction. The resulting material shows a BET surface area of 285 m 2 g -1 and a total volume of 0.65 cm 3 g -1 with abundant mesopores. Also, the P-CNTs exhibit good surface hydrophobicity with water contact angle o…

Large and segregated primary Si particles may drastically decrease the mechanical properties of Al-Si alloys. To solve this problem, a P-Cr complex modif ier was added into the alloy, and the effects of P-Cr complex modification and solidification conditions on the microstructure of hypereutectic Al-Si alloys casting…
以膨胀石墨（EG）为基体,聚乙二醇（PEG）为相变储热介质,利用EG对PEG良好的吸附性能,制备了PEG/EG/聚丙烯（PP）复合相变材料.采用傅里叶变换红外光谱（FT-IR）、扫描电镜（SEM）、差示扫描量热分析（DSC）等方法对复合相变材料的结构、形貌和热性能进行了表征.结果表明：EG吸附PEG后仍然保持原有疏松多孔的形态,PEG被EG均匀吸附.由于毛细管作用力和表面的物理化学吸附作用,PEG在固-液相变时很难从微孔中渗透出来.复合相变材料的流变、形态和热性能较好时PEG/EG/PP的质量比为73.2/1.8/25.0.
