Estimating the term…
This invention relates to a polyelectrolyte composition for a humidity sensor, polyelectrolyte ink and a preparation method of a polyelectrolyte membrane for a humidity sensor by inkjet printing. The polyelectrolyte composition according to this invention is composed of polyelectrolyte, crosslinking agent and organic solvent comprising a single component or in the form of a mixture of two or more solvents such as alcohols. The object of this invention is to provide a polyelectrolyte composition and a polyelectrolyte ink composition suitable for humidity sensor and a preparation method for a reliable humidity sensor with uniform thickness achieved through inkjet printing.
1-12. (canceled)
A polyelectrolyte composition for a humidity sensitive membrane of a humidity sensor, comprising 35-50 wt % of at least one compound selected from diamine-based compounds, 45-64.9 wt % of at least one compound selected from dihaloalkane-based compounds, and 0.1-5 wt % of at least one compound containing cross-linking functional groups.
A process for preparing a humidity sensor, wherein a polyelectrolyte ink is spread using an inkjet printing mode and then treated with heat to form a humidity sensitive membrane.
