WebSurface segregation of small amounts of additives in a polymer matrix is the most convenient and low-cost method to modify surface properties and functions. Although the surface segregation approach can increase the hydrophobicity of polymer surfaces, it is still a challenge to make the surfaces hydrophilic in an equivalent method. WebAll steps. Final answer. Step 1/2. Depolymerization or hydrolysis is the process of dissolving polymers into monomers. In this procedure, water molecules are utilised to dissolve the bonds that connect the polymer's repeating units, resulting in the production of distinct monomer units. View the full answer.
