In situ poly(sodium acrylate)‐based nanocomposite formation by redox‐initiated solution polymerization

Abstract

Polymer‐based nanocomposites have been widely investigated as a potential method to modify polymer and biopolymer properties. Poly(sodium acrylate) (PNaA)/nanosilver nanocomposites with 0.5, 1, 2, and 3 wt% nanofiller were prepared by in situ polymerization. The free radical, redox‐initiated, aqueous solution polymerization of NaOH‐neutralized acrylic acid was conducted in the presence of nanosilver. The progress of the polymerization was monitored using gravimetric conversion measurements. The addition of 0.5 wt% nanosilver to the polymerization resulted in a significant decrease in rate of polymerization The effect on rate was noticeably reduced when the experiment was repeated with nanoclay, a nonmetallic nanofiller, in lieu of nanosilver.

“…Assignments of peak locations to specific monomer and polymer microstructure are given in Figure . More details about the peak assignments and peak height changes during the polymerization were discussed elsewhere . Figure depicts conversion versus time measured for all nanocomposite samples as well as the pure polymer.…”

“…The samples were mounted onto metal stubs using graphite colloid double‐sided adhesive glue and were tested after being vacuum‐coated with a thin layer of gold. Additional details are provided elsewhere …”

“…Additional details are provided elsewhere. [7] Degree of hydrophilicity was determined by water contact angle measurements using the sessile drop method and each sample was measured for a minimum of 5 times (with a 2 mL distilled water droplet) to obtain the theta values.…”

“…More details about the peak assignments and peak height changes during the polymerization were discussed elsewhere. [6,7] Figure 3 nanocomposite samples as well as the pure polymer. Prediction of monomer conversion during nanocomposite formation from the ATR-FTIR data was achieved using a partial least squares calibration and is described elsewhere.…”
