Relaxation Dynamics of ABA Triblock Copolymer Hydrogels |
초록 |
PEO-based triblock copolymer hydrogels have been widely studied in various fields including drug delivery and tissue engineering due to high biocompatibility. Particularly, physically-crosslinked hydrogels composed of ABA triblock copolymers show great potentials as a 3D bio-printing material due to its superior injectability and biocompatibility. Here the reversibility of the phase-separated and dynamic interaction embedded in A end-blocks plays a crucial role to control the injectability and self-healing property. We demonstrate the relaxation dynamics of triblock copolymer hydrogels; they are driven by (1) hydrophobicity and (2) electrostatic interaction. Based on the observations, the results are discussed in terms of current understanding of block copolymer solution self-assembly and particular attention is paid to the issue of equilibration, given the chain dynamics of the core block. |
