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.

Copolymer dispersions containing polyamide segments in aqueous media form binders for coatings for various industrial and construction materials. The copolymers have a high percentage of amide linkages. The copolymers are linked into higher molecular weight species by reactions with polyisocyanates (which forms urea linkages if the other reactant is an amine or a urethane linkage if the other reactant is a hydroxyl group).
