Silver localization on polyimide using microcontact printing and electroless metallization
Abstract(#br)Silver localization is obtained on polyimide Kapton ® HN (PI) in step by step processes combining surface treatments (chemical and plasma), microcontact printing (μCP) and electroless metal deposition. There processes are developed in order to obtain silver patterns onto flexible polymer surfaces at the micro and sub-micro scale. Patterns of silver dots or, at the opposite, of holes in silver layer, were obtained using the same PDMS polydimethylsiloxane (PDMS) stamp (positive/negative technology). Processes are based on the same first step, i.e.
