experts through tensile test and found that using homogeneous elastomer substrate to cause micro cracks on the metal film, which ultimately damage to the transmission system.But if using polyurethane foam substrate, these cracks will only on the gas bubble at present, and in the bubble in the middle of the metal film will not be hurt, then conducting system is intact.Recently,
, a paper on polyurethane foam has attracted the attention of people, is the thin metal film covered in soft polyurethane foam substrate can improve mechanical and electrical performance, in the future to reach more than 100% of elastic do not harm the conductive system at the same time.
experts found after opening bubble stretching, causing cracks to fold elastomer thin layer focused on bubble hole above, and the changes will not affect other holes, it is convenient in the fine pore structure embedded electric conductor.Experts also said that after the metal film covered on polyurethane foam substrate can be stretched, and the experience is reversible and will not affect the electrical conductivity.It's for flexible electronic circuits (flexible electronic circuits) created the possibility.
