Topological effects of poly(glycidol)s for self-healing material based on the boronic ester |
초록 |
Self-healing polymers are able to shuffle dynamic covalent B-O bonds through transesterification and re-esterification under ambient humidity conditions. In this work, dynamic covalent bond (B-O) was introduced by addition of 4-Vinylphenylboronic acid into topology controlled poly(glycidol)s (PGDs) (i.e. cyclic branch PGD, hyperbranched PGD, and perfect linear PGD) and polymer networks were formed by simple radical curing process without initiator, which were confirmed by DSC, GPC, and NMR analysis. On the basis of the unique topologies of the PGDs, significant correlations between the topology and self-healing effects were investigated by nano-indentation and scratch tester. |
