Abstract:In this paper， from the perspective of multi-level hierarchical structures and physical-chemical modification methods of paper-based materials（PBM）， the research progress and development trend of PBM in water vapor barrier property were systematically summarized. Firstly， the particularity of water vapor barrier and the transport mechanism of water vapor molecules in different hierarchical structures of PBM were analyzed. Secondly， the research progress on the effect of 3D network internal structural modification on water vapor barrier property of PBM was discussed. Thirdly， based on the modification study of PBM interface structure， effect of various kinds of barrier coatings on the water vapor barrier property of PBM were compared and analyzed. Finally， the research status of super-hydrophobic paper-based materials was summarized， the synergetic and confrontational relationship between super-hydrophobic property and water vapor barrier property was discussed. Meanwhile， the necessity of improving the water vapor barrier property of super-hydrophobic PBM was dissected and the development ideas and directions for the real applications of super-hydrophobic PBM were proposed.
