Abstract:

Two kinds of highly-ordered hierarchical pore materials with large poresize of 40—80 μm and mesoporous phase in inner-wall were synthesized successfully using two kinds of natural plants as macroporous templat, P123 as mesoporous templat. The hydrothermal stability of the samples was investigated in 37 ℃ water. Scanning electron microscopy(SEM), powder X-ray diffraction(XRD), high-resolution transmission electron microscopy(HRTEM) and N2 adsorption/desorption are used to characterize the structure and properties of the products. The results confirmed that as-synthesized products own the macroporous and mesoporous phases. And the sample prepared with the stem of cattail as template shows good hydrothermal stability. This method can be used to replicate macroporous plant templates precisely. Since the aperture and pore structure of different plants are variable, it provides a natural condition for the synthesis of materials of different aperture holes and pore structure, and the organizational structure of the pore is to transport nutrient and water, so the hierarchical porous materials may have more superrior performance and application in the field of macromolecules separation, bone tissue regeneration ang drug delivery.
