Abstract: Gel polymer electrolyte compositions including a cross-linked three-dimensional polymer network and an electrolyte composition comprising an electrolyte and water are provided. The gel polymer electrolyte compositions can be included in an aqueous electrochemical cell, in which a gel polymer electrolyte can be positioned between an anode and a cathode. Methods of forming a gel polymer electrolyte in the form of a film are also provided. Methods of forming an aqueous electrochemical cell including a gel polymer electrolyte are also provided.

Abstract: A coating system may be configured to be applied to an aluminum-magnesium substrate of an object. The coating system may include a primer configured to reduce the corrosion rate of the aluminum-magnesium substrate and a topcoat configured to resist water and improve solar reflectance of the coating system. The primer may include a silicate and a first additive configured to increase corrosion resistance of the coating system The topcoat may include a siloxane and a second additive configured to reduce solar absorptance of the coating system.

Abstract: Example methods and articles of manufacture related to electrospun aramid nanofibers are provided. One example method may include forming a resultant solution by reacting a solution of aramids dissolved in a solvent with an electrophile. In this regard, the electrophile may perform a side chain substitution on the dissolved aramids. The example method may further include electrospinning the resultant solution to form an aramid nanofiber.
