a Photographs of water containing P(MAC-co-OEGMA) with 20 mol% MAC (i) before and (ii) after exposure to UV wavelengths of 300–400 nm for 1 h. The concentration of P(MAC-co-OEGMA) with 20 mol% MAC was 33 wt% in water. b Effect of the UV (300–400 nm) exposure time on the storage modulus (G’, closed circle) and loss modulus (G″, open circle) of the P(MAC-co-OEGMA) gel with 20 mol% MAC. The polymer concentration of P(MAC-co-OEGMA) with 20 mol% MAC was 28 wt% in PBS(−). c Effect of the polymer concentration on the storage modulus (G′, closed circle) and loss modulus (G″, open circle) of the P(MAC-co-OEGMA) gel with 20 mol% MAC. Aqueous P(MAC-co-OEGMA) solutions were exposed to UV for 1 h before the rheological measurements
