We report covalent single-walled carbon nanotube (SWNT) assembly into 3-dimensional framework materials with controllable pores. Thin films of SWNT framework multilayers having different sizes of linkers were synthesized via amidation and click chemistry, and characterized. The simple membrane-permeation experiment showed that the SWNT framework membrane with a larger linker molecule has a larger pore structure. This synthetic method was equally efficient on silica microspheres, resulting in all-SWNT hollow capsules after silica etching. We were able to further extend this strategy to encapsulating gold nanoparticles with SWNT framework cages. The ability to encapsulate functional nanomaterials inside perm-selective SWNT cages is an important step toward new applications such as hydrogen adsorbents, novel catalysis systems, and drug delivery vehicles. |
