Water nanocondensation on polymer single crystal-decorated buckypaper

摘要: Abstract Condensation on the surfaces of single-walled carbon nanotube (SWCNT) buckypaper and polymer single crystal-decorated was monitored in situ using an environmental SEM (ESEM). Water vapor pumped into chamber, backside cooling used to control sample surface temperature. In this way, condensation could be imposed sample. It found that, due different wetting states, contact angles all samples are significantly lower than static measured by sessile drop method. The polyethylene (PE) also strongly resists water condensation, thereby precluding flooding below fog point. Our results show that heterogeneous structure plays a key role determining condensation.
