摘要: AbstractIn this study, an iron oxide magnetic microparticles and poly(dimethylsiloxane) (MMPs-PDMS) composite material was employed to demonstrate a simple high-strength reversible bonding method. This paper presents the casting of opaque-view (where optical inspection through microchannels impossible) clear-view microchannel possible) MMPs-PDMS. The influence geometries on limited, which is similar standard PDMS casting. Clear-view performance highly associated with geometries. effects layout gap between cover layer micromold substrate were thoroughly investigated. Compared native strength 31 kPa, MMPs-PDMS experiments showed that thin film effectively reduced surface roughness enhanced magnetic...
