Abstract :
A series of poly(amide imide)s was synthesized to analyse the actuating behaviour using an interferometric method. Thus, different structures were used to obtain polymer films and composites. The results evidenced that for one polymer film the electromechanical nano-actuation had a value of -140 nm while for the composite polymer film with 20% ash powder the value was of 240 nm. The physical properties of the polymers were also investigated which showed high solubility in polar solvents, good film-forming ability, an initial decomposition temperature in the range of 355-510°C and glass transition temperature in the domain of 162-217°C.
