Abstract: The present disclosure describes a method of crosslinking fluoroelastomers, or more precisely thermally-crosslinkable fluorine-containing polymers, and to devices such as OTFTs (organic thin film transistors) incorporating such polymers. In some embodiments, a method comprises mixing: a solvent, a thermally crosslinkable fluorine-containing polymer, and one or more organic bases to form a mixed solution. The mixed solution is deposited over a substrate to form a first layer. The first layer is then crosslinked by thermal treatment to form a crosslinked first layer. The polymer is selected from: homopolymers of vinylidene fluoride; and copolymers of vinylidene fluoride with fluorine-containing ethylenic monomers. The one or more organic bases each have a pKa of 10 to 14.

Abstract: Laminates can comprise a substrate and a film. The film can comprise a film thickness from about 5 micrometers to about 400 micrometers and a tri-block copolymer comprising a first block positioned between two second blocks. The first block can be grafted with a first functional group. The first block can comprise a first glass transition temperature of about 0° C. or less. The two second blocks can each comprise a glass transition temperature of about 50° C. or more. A combined weight of the two second blocks can be from about 10 wt % to about 50 wt % of the tri-block copolymer. The film can comprise a refractive index from about 1.48 to about 1.55. Methods of forming a laminate can comprise disposing a film over a substrate. Methods can further comprise heating the film and the substrate to a first temperature and then a second temperature.

Abstract: Described herein are ultrasensitive gas sensors based on a vertical-channel organic semiconductor (OSC) diode, along with methods for making such devices, and uses thereof. The organic sensing layer comprises a fused thiophene-based organic polymer that connects top and bottom electrodes to deliver a vertical current flow. The nano-porous top-electrode structure enables the contact between ambient gas molecules and the vertical organic channel. The device has high sensitivity, is easy to process, and has a long shelf life.
