Surface Characterization of Oxygen-Plasma Treated POSS-based Acrylic Polymer Thin Films
For many applications, a combination of the properties of organic polymers with those of inorganic materials is desirable. the recently developed nanocomposite hybrid organic-inorganic materials based on polyhedral oligomeric silsequioxane (POSS) copolymers offer one avenue to exploit the best properties of both organic and inorganic materials. Applications involving higher glass transition temperatures, better flammability resistance, and resistance to degradation in low earth orbit have all been reported for POSS-based polymers. to date, no studies have been reported on the possibility of using these materials for microfluidic devices such as those needed for proposed micro total analytical (μ-TAS, or “lab-on-a-chip”) systems. However, modifying the surface chemistry of polymer microfluidic devices with the possibility of tailoring the surface wetting, biofouling, and electroosmotic flow (EOF) characteristics, and has been demonstrated with other surface modification strategies. the possibility of tuning the hydrophilicity and hence the EOF of POSS-based PMMA surfaces using an oxygen plasma is demonstrated in this paper.
