Abstract
Official abstract text for this publication.
A method of preparing a porous sheet includes mixing a matrix material dispersion including a matrix material dispersed in a first dispersion medium with a microorganism dispersion including microorganisms in a second dispersion medium, to form a mixture. The first and the second dispersion media are removed from the mixture to form a matrix sheet, and the microorganisms are decomposed from the matrix sheet to form the porous sheet.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of preparing a porous sheet of carbon nanotubes, comprising: adding a matrix material dispersion comprising carbon nanotubes dispersed in a first dispersion medium to a microorganism dispersion comprising microorganisms dispersed in a second dispersion medium; removing the first and the second dispersion media to generate a sheet of carbon nanotubes; and decomposing the microorganisms from the sheet of carbon nanotubes to form the porous sheet, wherein the decomposing comprises chemical treatment followed by freeze drying followed by thermal treatment. 2. The method of claim 1 , wherein the porous sheet includes multi-walled carbon nanotubes. 3. The method of claim 1 , wherein the microorganisms include E. coli. 4. The method of claim 1 , wherein the decomposing includes a bleach treatment followed by thermal calcination. 5. The method of claim 1 , wherein the microorganisms have a dimension of about 0.1 micrometers to about 30 micrometers. 6. The method of claim 1 , wherein the microorganisms have a dimension of about 0.1 micrometers to about 5 micrometers. 7. The method of claim 1 , wherein the matrix sheet includes spaces filled by the microorganisms, and wherein said decomposing the microorganisms forms pores in the porous sheet that correspond to the spaces. 8. The method of claim 1 , wherein the first dispersion medium and the second dispersion medium are different.
