Novel strategy for palygorskite/poly(acrylic acid) nanocomposite hydrogels from bi-functionalized palygorskite nanorods as easily separable adsorbent for cationic basic dye
Abstract A novel strategy was developed for the preparation of a palygorskite/poly(acrylic acid) nanocomposite (Pal/PAA) hydrogel with a 3-D network structure, by the surface-initiated redox radical solution polymerization of acrylic acid (AA) with the bi-functionalized palygorskite (BF-Pal) nanorods, in which the amino groups acted as the initiating groups, and the CC groups acted as the crosslinking groups. The effect of the synthesis conditions on the component in the Pal/PAA nanocomposite hydrogels were investigated with TGA analysis. The designed Pal/PAA hydrogel exhibited a remarkably high adsorption capacity for methylene blue (MB) of 833.9mg/g.

Highlights Pal/PAA nanocomposite hydrogels with 3-D network skeleton were designed. BF-Pal nanorods were used as both initiator and crosslinker. The hydrogels show remarkably high adsorption capacity for MB of 833.9mg/g. They can deposit within 30min after the adsorption of MB.
