Abstract
Molecule transfer in the nanoconfined space is a common issue in the modern chemical process. However, surface wettability and confined degree in nanoconfined space lead to the effect of asymmetry of the molecular interaction. Such symmetric interaction induces the inhomogeneous and further causes the unavailable of the classical transfer theory. The lack of the transfer theory oriented to the limit can no longer meet the needs of the development of modern industry. This paper summarizes the research work of our team and the frontier of confined transport, and analyzes it based on statistical mechanics and non-equilibrium thermodynamic methods. It is found that the frontier research covers three perspectives. Namely, molecular interaction determines the abnormal fluid state in new free degrees, the abnormal fluid state-dependent fluid transfer phenomenon further decides the confined fluid resistance of fluid transfer. Based on three perspectives, the primary theory of confined transfer resistance is concluded. Furthermore, the primary theory of confined transfer resistance is used to analyze hot research in nanoconfinement conducted by advanced experimental and theoretical works. Finally, this work proposed that combining three perspectives, in terms of the fluid state in the space, may give a framework to develop the nanoconfined transfer theory for guiding the development of modern chemical engineering.
