The present invention provides a method of forming paracyclyophane containing disulfide functional group. The paracyclophane is prepared by adding 3,3-dithiodipropionic acid (DPDPA) and N-ethyl-N-(3-(dimethylamino)propyl)carbodiimide (EDC) into 4-aminomethyl [2,2] paracyclophane. The present invention further provides a chemical film and a method of forming the same. The chemical film contains poly-p-xylylene with disulfide functional group and is formed on a substrate by a chemical vapor deposition process.
