• Description: Poly(vinylsulfonic acid, sodium salt) is a polymer that consists of repeating units of vinylsulfonic acid monomers, where each vinylsulfonic acid unit is neutralized with a sodium cation (Na+).; Poly(vinylsulfonic acid, sodium salt) is an example of a polyelectrolyte, which is a type of polymer that contains ionizable groups along its chain. The presence of sulfonic acid groups (-SO3H) in this polymer provides it with strong acidic properties. However, when the polymer is neutralized with sodium ions, it becomes water-soluble and exhibits enhanced solubility and stability in aqueous solutions.

Case Study

Synthesis of Hydrogel Matrix From PVSA for Preparation of Antibacterial Materials

Varaprasad K,et al. Journal of Applied Polymer Science, 2011, 121(2): 784-796.

In order to develop new hydrogel silver nanocomposites with greater applicability for antibacterial applications, poly(vinyl sulfonate sodium salt) (PVSA) has been used to prepare the hydrogel matrix in this antibacterial material.
Preparation PVSA-based hydrogels
· Add 0.10g PVSA sodium salt and 1mL TA (1g/100mL, 4.01×10-3mM) to a certain concentration of Acrylamide solution.
· Free radical crosslinking polymerization was carried out by adding 1 mL of ammonium persulphate (APS) (5 g/100 mL, 2.19×10-3 mM) and 1 mL of N,N,N',N0''-tetramethylethylenediamine (TMEDA) (1 g/100 mL, 1.72×10-3 mM) as redox-initiating pair. To obtain a complete network throughout the hydrogel, the polymerization reaction was continued for 8 h.
· The formed hydrogel sample was taken out and washed with distilled water to remove unreacted monomer/polymer. PVSA-based hydrogel was obtained after drying treatment.
· By further adding silver ions and reducing silver ions to the hydrogel sample, an antibacterial composite material can be obtained.
