# Prepare an aqueous solution of 13% PVA and 0.02% sodium alginate at 60°C | |||
## 1 gram of PVA and 0.16 g of sodium alginate in 7 mL of water (12.5% PVA and ~0.02% alginate) | |||
## ~0.1 g of nanocomposites should be added to this mixture where applicable | |||
# Cool dissolved and mixed solution to 35°C | |||
# Prepare 210 mL of saturated citric acid with 2% calcium chloride | |||
## Add 4.2 grams of calcium chloride to 210 mL of water | |||
## Add citric acid to saturation | |||
# Add the PVA-Alg-Nanocomposite mixture drop-wise to the gently stirring citric acid-calcium chloride solution using a thin needle | |||
# Stir for 24hrs to allow solidification | |||
# Rinse with water to remove excess reactants | |||
