By means of aqueous solution polymerization method, the composites of polyacrylic acid (PAA)/Bacterial cellulose (BC)/Na-MMT and PAA/Na-MMT were prepared respectively. The effects of Na-MMT content on the properties of PAA/Na-MMT and BC content on the properties of PAA/BC/Na-MMT composites were investigated. The results show that with appropriate increasing Na-MMT, the composites has good salt-resistant ability and thermal stability, mean while, the water-absorbing capacity of PAA/Na-MMT composites is significantly increased. Comparing with that of the PAA/Na-MMT hydrogel, with addition of BC content, the water-absorbing capacity and thermal stability of PAA/BC/Na-MMT are enhanced in a certain degree. The SEM analysis indicate that there are more network structure in the composites hydrogel. XRD result shows that the layered structure of Na-MMT is stripped and the prepared composites achieves peel compound.
