title: A Stiff and Healable Polymer Based on Dynamic-Covalent Boroxine Bonds.
abstract: 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.
