Abstract
The method of making polyacrylamide (PAM) aerogel are described. Different ratios of PAM in the construction of aerogels were tested. The material was tested for water retention after drying. freeze-dried aerogel samples especially PAM 15 wt %, have a higher swelling ratio with a faster water absorption rate compared to gel and oven-dried samples.
