Polyurethane Poly(2-(Diethyl Amino)Ethyl Methacrylate) blend for drug delivery applications
(2015)
A pH-sensitive blend of polyurethane (PU) and poly(2-(diethyl amino)ethyl methacrylate (PDEA) with good film-forming capacity was prepared from the corresponding aqueous dispersions. The polymer matrix was first characterized ...
The role of nanocrystalline cellulose on the microstructure of foamed castor-oil polyurethane nanocomposites
(2015)
Nanocrystalline cellulose (CNC), obtained by sulphuric acid hydrolysis, was used to synthesize polyurethane foams (PUFs) based on a functionalized castor oil polyol and a Methylene diphenyl diiso- cyanate (MDI). Formulations ...
Morphology and properties of neutralized chitosan-cellulosenanocrystals biocomposite films
(2016)
Chitosan/cellulose nanocrystals (CH-CN) films were obtained by casting of dispersions, and treated with NaOH for neutralization proposes. The composition of films was varied from 1 to 10 wt.% of CN. Changes in the morphology ...
