Table 3
Effect of the degree of ionization α on the percentage of P4VPS introduces into bentonite on the interlamellar space.
| | Sample | α | Polymeric salt content (%) | d (nm) | 2θ (°) |
| | Bentonite | 0 | — | 1.38 | 6.39 | | P4VP/MMT [37] | 0 | 7.2 | — | — | | P4VPS1/MMT | 0.1 | 8.6 | 1.47 | 5.98 | | P4VPS2/MMT | 0.25 | 9.5 | 1.47 | 5.98 | | P4VPS3/MMT | 1 | 9.6 | 1.49 | 5.90 | | P4VPS4/MMT | 1.5 | 7.1 | 1.50 | 5.88 |
