Description

Verfahren zum Leitendmachen nichtmetallischer Oberflächen, insbesondere von Kunststoffen Es ist bekannt, z. B. Glas dadurch lekend zu machen, daß man auf seiner Oberfläche Bleisulfid in spiegelnder Form niederschlägt, wobei man sich z. B. einer alkalischen Bleilösung bedient, der Thioharnstoff zugcsetzt wird. Dieses Verfahren ist jedoch mit dem Nachteil behaftet, daß die Schicht#en verhältnismäßig schlecht leiten. - Es wurde nun gefunden, daß man die Leitfähigkeit solcher Bl#isulfidschichten jedoch bedeutend verbessern kann, wenn man sie kurzzeitig in verdünnter Silbersalzlösung, z. B. Silbernitratlösung taucht. So vorbehandelte 131,eisulfidschichten lassen sich mit viel geringerem Spannungsaufwand verkupfern als nicht vorbehandelte.Process for making non-metallic surfaces conductive, in particular plastics. B. to make glass thereby lekend that one precipitates lead sulfide in a reflective form on its surface, one z. B. an alkaline lead solution is used to which thiourea is added. However, this method has the disadvantage that the layers conduct relatively poorly. - It has now been found that the conductivity of such blood sulfide layers can, however, be improved significantly if they are briefly in a dilute silver salt solution, e.g. B. Silver nitrate solution dips. 131 ice sulfide layers pretreated in this way can be copper-plated with much less stress than those that have not been pretreated.
