| Afterwards, the generated floccule was deposited using EDC and Sulfo-NHS and washed with acetone after centrifugation. |
|
| The floccule stuff is also observed in the products as shown in Figure 7a, which is in agreement with the results of SEM characterization. |
|
| After that, the floccule was collected, washed with distilled water and ethanol several times to remove ions and possible remnants in the final product. |
|
| The flame retardant performance was achieved through the formation of a relatively uniform network-structured floccule layer covering the entire sample surface without any cracks or gaps. |
