摘 要：Biporous nanocarbon foams （NC foams） which have both nano-pores and micro-pores,were fabricated and used to explore the liquid transportation in the porous structures formed by *** electron microscopy was utilized to observe the structure of the NC *** rise tests using acetone as the working fluid were conducted by the IR thermal imaging *** results show that the capillary rise height of the NC foam with 65μm micro-pore size was 47%higher than that with 9μm micro-pore size in 50 *** capillary performance of the NC foams was reduced when its density was higher than 60 mg/cm;.A model is built to illustrate the effect of both nano-structure and micro-structure on the transportation of working fluid in the biporous *** data indicates that the nano-structure generated high capillary pressure while the microstructure provided low resistant pathways for fast liquid *** size of micro-pores and the ratio of micro-pores to nano-pores were two important *** is demonstrated that the NC foams had large sorption capacity up to 878 mg/cm;and their capillary performance was further enhanced when using a substrate.
