FT-IR spectra of the expanded perlite, sodium polyacrylate resin, and composite materials are given within the Figure 2. From the determine, the characteristic of -OH bond absorbed around 3748 and 2924 cm−1, suggesting all of the samples had a capacity for dehydration condensation with -COOH. Figure three shows answer absorbency (g/g) of the c […] View
