    • In general, the semi-IPN hydrogel is prepared as indicated by the following two methods: (i) The first monomer is polymerized and cross-linked to prepare the hydrogel, and then polymerization of the second monomer is carried out inside the hydrogel, ii) The hydrogel is immersed in the polymer solution so that the linear polymer chains can penetrate into the hydrogel network

    • When HM(N50H50, N96C4) was compared to HMN50H50, the average size of the former was smaller than that of the latter. This is because the particle size of the coacervate droplets induced in the N50H50-Ns 96C4 binary system was smaller than that induced in the one-component N50H50 aqueous system as shown in Figure 8a

    • Strictly speaking, if there are even a few linear chains in the gel matrix, it corresponds to a semi-IPN structure by definition. In this study, however, the semiIPN structure was defined as the hydrogel microsphere only including a sufficient number of linear poly(NIPAAm-co-CIPAAm) chains enough to provide the gel matrix with their features, such as the improvement of dispersibility and the fluorescence emission
