Is gelatin ionic or covalent
WebThe dynamic covalent boronate ester bonds and ionic gelation in presence of divalent cations allowed a modular crosslinking with suitable rheological and mechanical properties for biomimetic 3D scaffolds. Injectable DN hydrogels were prepared from CS quaternary ammonium salt and Alg-Na by electrostatic interaction and ionic crosslinking . The ... WebFeb 5, 2014 · This is either because the covalent bond is strong (good orbital overlap) or the ionisation energies are so large that they would outweigh the ionic lattice enthalpy. If they form an ionic bond then that is because the ionic bond is stronger than the alternative covalent bond. This is either because the covalent bond is weak (poor orbital ...
