| Abstract: | Montmorillonite /polyacrylamide (MMT/PAM) humidity control materials, with the MMT modified separatly by argent-ammonium complex ions (Ag(NH3)2]+) and copper ions (Cu2+) (Ag-MMT/PAM, Cu-MMT/PAM) were prepared. The structures of the Ag-MMT/PAM and Cu-MMT/PAM were characterized with X-ray diffraction (XRD), Fourier transform infrared spectra (FTIR) and scanning electron microscopy (SEM). The humidity control property was examined by a desiccator method. Antibacterial properties were tested with an inhibition zone method. The results showed that the structures of Ag-MMT/PAM and Cu-MMT/PAM were loose and porous. Polyacrylamide was intercalated into the layers of the MMT. The increasing interlayer spacings of Ag-MMT/PAM and Cu-MMT/PAM were from 1.51 nm for the original MMT to 2.04 nm and 2.11 nm, respectively. Both Ag-MMT/PAM and Cu-MMT/PAM presented good humidity control and antibacterial properties. |
