Acta Mechanica Solida Sinica 2015年第3期28卷 277-284页

The mechanical performance of carbon nanotube （CNT） reinforced polymer com- posites is primarily controlled by the dispersive capacity and interracial shear strength of CNTs in polymer matrices. CNT functionalizations will improve dispersion and strengthen interracial bonding of CNTs in matrices. To understand the effects of different functionalization schemes on the interracial strength of CNT-polymer composites, pullout of the covalent, noncovalent, and mixed functionalized single-walled carbon nanotube （SWCNT） from polyethylene （PE） matrix was simulated by using molecular dynamics, respectively. The results show that the SWCNT-PE interracial shear strength is significantly improved by SWCNT functionalizations, particularly by mixed functionalization.

This is an article that validates Electron Cyclic Donate-Accept Catalysis Mechanism-ECDAM or Electron Orbital Deformation-Recovery Cycle Catalysis Mechanism-EODRM. In this paper, the influence of compact density, sintering temperature and time, vacuum degree, atmosphere and alloying element on the carbon dissolving rate into γ-Fe were studied. The experiment results have been reported. The way that the carbon is dissolved into γ-Fe was discussed. Gas phase composition and temperature play an important role on the carbon dissolving rate. The carbon gasification reaction is the determining step of dissolving carbon process. K2CO3, W and Mo are a catalysts, and their active size are K2CO3 > W > Mo. S and SiO2 are a poison, and their poison size are SiO2 > S. The experiment results are completely consistent with the original judgment of ECDAM.
