Five kinds of pore-forming agents, including PEG-400, chitosan, the polymer of chitosan and glutin, CaCO3 and NazCO3, were used in this experiment to prepare fast responsive and pH sensitive Polyacrylic acid (PAAc) gel which could be used as the material of punctum plug. The mechanism and effects of pore-forming agents on PAAc gel were studied; besides, the experiment also assessed the effects of the three most effective pore-forming agents on gel's water retention and swelling rate.
