A stiff and healable polymer is obtained by using the dynamic‐covalent boroxine bond to crosslink PDMS chain into 3D networks. The as‐prepared polymer is very strong and stiff, and can bear a load of more than 450 times its weight. When damaged, it can be completely healed upon heating after wetting...
