Hydrophobic melamine sponge prepared by direct fluorination for selective absorption |
| 초록 |
Fluorination was performed to improve the selective absorption capacity of melamine sponges (MS) for various solvents in industrial wastewater. The direct fluorination method is a simple method for introducing fluorine into the polymer surface. The surface fluorine content of the fluorinated melamine sponge (F-MS) increased by up to 31% compared to the untreated melamine sponge. However, despite the increase in the amount of fluorine gas, the surface fluorine content of the F-MS was similar. The morphology of the F-MS was investigated by SEM. It was determined that the MS structure was broken as the amount of fluorine gas increased, which is presumed to be damaged by a chain reaction of fluorine gas. The absorption capacities and selectivities of untreated MS and F-MS for various solvents were investigated. It was revealed that the untreated MS absorbed water, and the F-MS was unable to absorb water due to the inflow of fluorine. |
