摘要
A linear silicone elastomer was synthesized via a one-pot and noncatalytic aza-Michael reaction. Noncovalent boron-nitrogen coordination bonds formed the reversible crosslinking network. The formation of the elastomer was confirmed using FT-IR, XPS, and scanning electron micrographs. The prepared material could repair spontaneously and rapidly without any external energy, and the good original mechanical properties were maintained. The reversible B-N coordination bonds were used for the first time in self-healing, and the elastomer could be remolded.
