PDMS-弹性体

Abstract(#br)Medical grade polydimethylsiloxane (PDMS) elastomer is a widely used biomaterial as encapsulation and/or as substrate insulator carrier for long term neural implants because of its remarkable properties. Femtosecond ( λ \u003cce:hsp sp=\"0.25\"/\u003e=\u003cce:hsp sp=\"0.25\"/\u003e263 and 527\u003cce:hsp sp=\"0.25\"/\u003enm) and nanosecond (266 and 532\u003cce:hsp sp=\"0.25\"/\u003enm) laser processing of PDMS-elastomer surface, in air, is investigated.

Abstract(#br)Medical grade polydimethylsiloxane (PDMS) elastomer is a biomaterial widely used in medicine and high-tech devices, e.g. MEMS and NEMS. In this work, we report an experimental investigation on femtosecond laser processing of PDMS-elastomer with near infrared (NIR), visible (VIS) and ultraviolet (UV) pulses. High definition trenches are produced by varying processing parameters as laser wavelength, pulse duration, fluence, scanning speed and overlap of the subsequent pulses.
