摘要:
A process for producing a sensor component for detecting an analyte; a sensor component producible by the process; a process for detecting an analyte; and a device comprising the sensor component. The process comprises electrochemically growing a plurality of conducting polymer molecules from a monomer electrolyte solution to provide a percolation network. The plurality of conducting polymer molecules are grown on the surface of an insulating substrate to connect a first electrode to a second electrode and are capable of displaying a change in an electrical property in response to interaction with an analyte A plurality of conductive nodes may be disposed on a surface of the insulating substrate. A potentiostatic method or a galvanostatic method may be employed to grow the plurality of conducting polymers. Chronoamperometry may be employed to electrochemically grow the plurality of conducting polymers. Cyclic voltammetry is not employed to grow the plurality of conducting polymers.

摘要:
Described herein are facile, one-step initiated plasma enhanced chemical vapor deposition (iPECVD) methods of synthesizing hyper-thin (e.g., sub-100 nm) and flexible metal organic covalent network (MOCN) layers. As an example, the MOCN may be made from zinc tetraphenylporphyrin (ZnTPP) building units. When deposited on a membrane support, the MOCN layers demonstrate gas separation exceeding the upper bounds for multiple gas pairs while reducing the flux as compared to the support alone.

摘要:
A polymerization initiator, a first polymerizable compound, and a second polymerizable compound are poured into a hollow of a first member (12). The first and second polymerizable compounds are copolymerized to produce a second member (16). The second member (16) is produced by forming a first layer (21) on an inner wall of the first member (12) and sequentially forming a layer over a precedingly formed layer. To form each layer, the first and second polymerizable compounds are put in the hollow of the first member (12), satisfying 1/99≦W2/(W1+W2)≦⅔ when W1 is a weight of the first polymerizable compound, and W2 is a weight of the second polymerizable compound. The first and second polymerizable compounds are mixed such that the value of W2/(W1+W2) increases from the first layer (21) toward an nth layer.
