In an example of a method disclosed herein, a polycarbonate with a hydrophilic surface is formed. An ether substituted dichlorosilane, phosgene, and a Bisphenol reactant are polymerized to form a polycarbonate including a hydrolyzable silane in its backbone chain. The hydrolyzable silane includes an alkoxy group attached to a silicon atom. The alkoxy group on the hydrolyzable silane is converted to a more hydrophilic functional group to form the polycarbonate with the hydrophilic surface.
