Abstract: 

Thin films of bilayer poly(divinyl benzene) p(DVB)/poly(perfluorodecylacrylate) (p-PFDA) are synthesized via iCVD on steel and silicon substrates. Nanomechanical measurements reveal that the elastic modulus and hardness of the films are enhanced through the bilayer structure and that the adhesion of the films to the substrate is improved via in-situ grafting mechanism. Strength of ice adhesion to the substrates is reduced more than six-fold when the substrates were coated with bilayer polymers.
