Hydrolytic, thermal and radiation stability of modified urea-formaldehyde composites: influence of montmorillonite particle size
(Elsevier, 2022-06-15)
Urea-formaldehyde (UF) composites with a formaldehyde/urea (FA/U) ratio = 0.8 and different particle sizes of montmorillonite (MMT), namely UF/KSF and UF/K10 were synthesized. The hydrolytic stability of modified UF ...
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 ...
