Doping graphene to epoxy resins can improve the protective ability of the coating, but the lack of active anticorrosion function greatly limits its application in the field of anticorrosion. Herein, N/S-rich few-layer-graphene (N/S-FLG) was prepared and adopted to endow epoxy coating with dual passive/active corrosion protection. The obtained amphiphilic N/S-FLG is highly dispersed in the epoxy coating, giving rise to the enhanced hosting effect for graphene defects, avoiding the interface corrosion and blocking the penetration of corrosive species. Furthermore, the doping of N and S endows graphene sheets favourable catalytic ability for corrosive oxygen, actively eliminating its contribution to metal corrosion. Under this dual effect, the passive and active anticorrosion properties of epoxy coating are simultaneously enhanced. The coating with 1 wt% N/S-FLG reduces the corrosion rate of metal to 6.5 × 10– 5 mm/a, exhibiting almost no corrosion. The proposed concept of introducing nanocatalytic N/S-FLG is facile and eco-friendly, and will undoubtedly promote the practical application of anticorrosion coatings.

This article explores whether China is ready to comply with its international obligations to recognize and enforce investment arbitral awards, and if not, what remains to be done. First, for ICSID awards, China has neither enacted any implementing legislation, nor designated courts or authorities are competent at recognizing and enforcing ICSID awards. Second, it is more ambiguous and complicated to seek recognition and enforcement of non-ICSID awards, due to China’s commercial reservation to New York Convention. It is uncertain whether the current provisions in national law on the recognition and enforcement of foreign commercial arbitral awards would also apply to the recognition and enforcement of non-ICSID awards. Moreover, statutes on State immunity, the common issue while enforcing both ICSID and non-ICSID awards, are quite insufficient. Finally, beyond satisfying its international obligations, investment arbitral awards issued by Chinese arbitration institutions also face obstacles of recognition and enforcement.
