Transient deformation and swelling of paper by aqueous co-solvent solutions

Abstract

Inkjet printing inks frequently contain polar liquids of low volatility such as glycerol or poly(ethylene glycols) in addition to the main solvent water. The deposition of these liquids on paper...

“…Moreover, it was reported in Ref. [56] that the persistent expansion strain deposition and evaporation of various aqueous co-solvent solutions monotonically increased for low co-solvent concentrations up to a critical value between 40 and 60 wt%, beyond which it monotonically decreased. This critical value did not seem to depend strongly on the chemical composition nor the MW of the co-solvents considered in Refs.…”

“…This critical value did not seem to depend strongly on the chemical composition nor the MW of the co-solvents considered in Refs. [21,56]. The co-solvent MW therefore appears to primarily affect the values of 𝑘 𝑝𝑓 and possibly also of 𝑓 𝑞 and 𝑞 𝑟 , but not so much 𝑐 crit .…”
