Eco-friendly process for facile pore control in thermally stable cellulose acetate for application to battery separator |
| 초록 |
The pores in cellulose acetate polymers for battery separators or water-treatment membranes were easily generated by utilizing both hydrated metal salts and water pressure. When cellulose acetate polymer film containing hydrated metal salts was exposed to water pressure, the continuous straight pores were generated. These results could be explained by that cellulose acetate polymer chains became weakened due to the plasticization effect by the hydrated parts in polymer. Furthermore, pore size could also be easily controlled by controlling the strength of water pressure. The generated pores in CA polymers were confirmed by scanning electron microscopy (SEM) images. The suggested process could be evaluated as eco-friendly technology since the metal salts used could be reused by evaporation of water. |
