Hydrophobic bonds
WebNoncovalent bonding is the dominant type of bonding in supramolecular chemistry. These noncovalent interactions include: ionic bonds, hydrophobic interactions, hydrogen bonds, Van der Waals forces, i.e. "London dispersion forces", and Dipole-dipole bonds. WebThe method for fixing the hydrophilic polymer on the hydrophobic surface by bonding the hydrophilic species to the hydrophilic polymer comprises a step for exposing the hydrophilic polymer to the hydrophilic species so as to bond the hydrophilic species on the hydrophilic polymer, a step for forming a hydrophobic surface and a step for fixing the …
