Web12 apr. 2024 · PVA is a widely used water-soluble and biocompatible synthetic polymer [ 5, 6 ]. Hydroxyl groups on PVA chains could form a large number of intramolecular and intermolecular hydrogen bonds, which impart good adhesion, barrier properties and emulsifying properties to PVA. WebThe presence of hydrogen bonding between molecules of a substance indicates that the molecules are polar. This means the molecules will be soluble in a polar solvent such as water. Some examples of polar molecules which can hydrogen bond are ammonia ( N H 3) and methanol ( CH 3OH ).
