제목 How do geometries of crosslinking units influence the polymer networks?
초록 This study investigates the influences of crosslinking geometries on polymer networks. The geometry effects were evaluated between linear and triangular bindings using catechol-based coordination bonds. Tetra-arm-PEG with catechol end (4-PCA) networks were prepared with bis- and tris-complex coordination bonds through iron cations. Their chemical structure, physical properties, and nanostructures were examined. The results show that the isotropic geometry of 4-PCA corresponds to the linear bindings. Otherwise, triangular units lead to the distortion of 4-PCA networks, showing longer correlation lengths and micro-scaled defects. This study provides insight to develop novel polymer gels, of which binding units control the structural characteristics.
