increased or decreased by the amount and type of additive the mechanical properties such as tensile properties modulus impact resistance etc can be tuned as described above the additive can range from 0 001 to 90 by weight more preferably from 0 001 to 50 and most preferably from 0 001 to 25 a list of plasticizers that can be used to practice the present invention is given in table 1 the plasticizer can be small molecules oligomeric or polymeric in nature as can be seen in table 1 they can be monofuntional bifunctional and multifunctional the additive can also be removed from the final film structure if so desired by appropriate extraction polyaniline synthesis polyaniline is synthesized by the oxidative polymerization of aniline using ammonium peroxydisulfate in aqueous hydrochloric acid the polyaniline hydrochloride precipitates from solution the polymer is then neutralized using aquoeous ammonium hydroxide the neutralized or non dope polyaniline base is then filtered washed and dried polyaniline can also be made by electrochemical oxidative polymerization as taught by w huang b humphrey and a g macdiarmid j chem soc faraday trans 1 82 2385 1986 polyaniline base in nmp the polyaniline base powder is readily dissolved in nmp up to 5 solids thin films on the order of a micron can be formed by spin coating thick films are made by solution casting and drying 70 u00b0 c in vacuum oven under a nitrogen purge for 15 hours these solutions and films have the properties described above a polyaniline base was first dissolved in nmp to 5 solids and allowed to mix well a poly co.
