Effect of oxygen-containing functional groups in epoxy/reduced graphene oxide composite coatings on corrosion protection and antimicrobial properties Original Research Article Applied Surface Science, Available online 16 April 2018, Pages Ming-Hui Wang, Qihong Li, Xiaogang Li, Yongchang Liu, Li-Zhen Fan
Graphical abstractReduced graphene oxide (RGO) sheets with different contents of oxygen-containing functional groups are prepared by controlling the reduction time in oxidation-reduction reaction. Results show that the structure, dispersion, and surface properties of RGO sheets are controlled by the number of oxygen-containing functional groups. The epoxy-based composite coating reinforced by 0.25 wt% RGO with 1 h reduction (EP/RGO1h) exhibits excellent corrosion protection behaviors due to synergism of the barrier effect, impenetrability, and hydrophobicity. Meanwhile, epoxy/graphene oxide (EP/GO) composite coating shows antimicrobial potential due to the oxidative stresses. This work provides a promising avenue to achieve novel graphene-based corrosion protection and antimicrobial composite coatings.

Graphical abstract

Benefit from the strong synergistic electronic effect between Co and CeOx, as well as the strong metal-support interaction between Co-CeOx and 3D NGH, the as-synthesized Co-(CeOx)0.91/NGH catalyst exhibits excellent catalytic activity toward hydrolysis of ammonia borane, with the turnover frequency (TOF) value of 79.5min−1. | Reduced graphene oxide wrapped alluaudite Na2+2xFe2-x(SO4)3 with high rate sodium ion storage properties Original Research Article Journal of Alloys and Compounds, Available online 16 April 2018, Pages Min Zhang, Hui Qi, Hailong Qiu, Tong Zhang, Xiaosen Zhao, Huijuan Yue, Gang Chen, Chunzhong Wang, Yingjin Wei, Dong Zhang | Tunable-Sensitivity Flexible Pressure Sensor based on Graphene Transparent Electrode Original Research Article Solid-State Electronics, Available online 16 April 2018, Pages Shi Luo, Jun Yang, Xuefen Song, Xi Zhou, Leyong Yu, Tai Sun, Chongsheng Yu, Deping Huang, Chunlei Du, Dapeng Wei | |
