The influence of the modification of the montmorillonite KSF and K10 on the hydrolytic stability of UF composites
(2021-09-24)
In this work, the hydrolytic stability of composites based on the urea-formaldehyde resin (UF) and montmorillonite-MMT (K1 0 and KSF) as a formaldehyde (FA) scavenger was investigated. K10 and KSF were activated by sodium ...
Synthesis and characterization of pH-sensitive Saccharide modified polyurethane hydrogels – Effect of polyol, crosslinker and acid chain extender
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2021-07-10)
Biodegradable polyurethanes can be the basis for drug delivery systems that
are sensitive to external changes. pH-sensitive polyurethanes (PUs) have been
used successfully as intravaginal rings and specific drug delivery ...
