A composition comprising: A) polymer that comprises: L is CX—CYZ, where X, Y, and Z are independently hydrogen, an alkyl, or a substituted alkyl; and, M is an alkylene, an arylene, a substituted alkylene, a substituted arylene, or C(O)O—W—, where W is an alkylene or a substituted alkylene; and R′, R″, and R′″ are independently selected from an aromatic hydrocarbon, an aliphatic hydrocarbon, or a substituted hydrocarbon that comprises one or more of O, N, S, or Si atoms, provided that at least one of R′, R″, and R′″ is selected from alkoxyl, aryloxyl, hydroxyl, halide, carboxyl, or carbonate; and, p is from 1 to 10,000; and the polymer does not comprise a polyhedral oligomeric silsesquioxane structure; and B) a polymer formed from a composition comprising at least one Si-containing compound as described herein. Compositions are suitable for microelectronic applications, and have improved adhesion to photoresists polymers.
摘要:
Bioelectrodes, methods of making bioelectrodes and methods of using bioelectrodes are provided. The bioelectrodes have an electrically-conductive substrate coated with an electroconductive polymer. The bioelectrode exhibits ohmic behavior over a range of about 1 Hz to about 100 KHz, where ohmic behavior means that the value of the impedance is independent of the signal frequency over the range of interest. The bioelectrode can transmit or receive an electrical signal between the electrically conductive substrate and the biological component through the conductive polymer.
