Figure 5. — Characterization of the synthesized NIPAAm-co-ATBA_0.35@SiO₂. (a) Nitrogen adsorption and desorption isotherm curves of porous silica gels before (black) and after (red) modification with NIPAAm-co-ATBA_0.35 copolymer; the inset shows the corresponding pore size distribution. (b) Thermal gravimetric analysis (TGA) curves of amino- (black) and NIPAAm-co-ATBA_0.35 (red) modified silica gels. (c) Elemental analysis data of NIPAAm-co-ATBA_0.35@SiO₂. The oxygen content in the copolymer was calculated by combining the elemental analysis and TGA data; (d) PH-dependent zeta-potential change curves of NIPAAm-co-ATBA_0.35@SiO₂ before (black) and after complexation with BSA (red) or α-casein (blue).
