| 논문초록 | Understanding and controlling the interaction between water and a surface is the key factor in designing hydrophilic films for antifogging and antifouling applications. Here, in a nanostructured hydrophilic film comprising of chitosan(CHI) and carboxymethyl cellulose(CMC), we demonstrate the effect of a new design element, oligo(ethylene glycol)(OEG) grafting on CHI(CHI-lin), on the antifogging and antifouling performances. By comparing the CHI-lin/CMC films with chemically cross-linked CHI/CMC films, we show that the water contact angle value does not satisfactorily serve as a direct indicator of antifogging and antifouling properties. Moreover, we demonstrate that the OEG groups within the film provide active sites for the water to strongly interact with, inhibiting fogging and cell adhesion. We also conduct a mechanistic study using differential scanning calorimetry and X-ray absorption near edge structure to directly probe the functional moieties that strongly interact with water. |
