PVA-Alg-NaMT (no citric acid) | |||
# Prepare an aqueous solution of 13% PVA and 0.02% sodium alginate at 60°C (Stir plate on 3rd setting: ~68°C) | |||
#* '''1 g of PVA''' and '''0.16 g of sodium alginate''' in '''7 mL of water''' (12.5% PVA and ~0.02% alginate) | |||
##* Add alginate '''while stirring''' PVA-water solution | |||
#* '''~0.1 g of NaMT''' and '''~0.05 g AC''' should be added to this mixture where applicable | |||
# Cool dissolved and mixed solution to 35°C | |||
# Prepare 210 mL of saturated citric acid with 4% calcium chloride | |||
## Add '''8.4 g (4%) calcium chloride''' to 210 mL of water | |||
# Add the PVA-Alg-Nanocomposite mixture drop-wise (by syringe) to the gently stirring (stir plate 3) citric acid-calcium chloride solution using a Pasteur pipette | |||
# Stir for 2 hrs to allow solidification | |||
# Rinse with water to remove excess reactants | |||
