Polyurethane elastomers-based modified castor oil and poly( -caprolactone) for surface-coating applications: Synthesis, characterization, and in vitro degradation
(Journal of Elastomers and Plastics, 2014)
Polyurethanes (Pus) were synthesized from castor oil and modified through transesterification by pentaerythritol, poly(ε-caprolactone)diol (PCL), and isophorone diisocyanate to form PU coatings. The ratio of NCO/OH groups ...
Biodegradation of polyurethane derived from castor oil
(Associação Brasileira de Polímeros, 2008)
The aim of this research was to study the biodegradation of a polymer derived from castor oil, which is a renewable, natural material that is a practical alternative for the replacement of traditional polyurethane foams. ...
Characterization of nanocellulose- reinforced shape memory polyurethanes
(John Wiley & Sons Ltd, 2008-04)
Background: Shape memory polymers are capable of fixing a transient shape and of recovering their original dimensions by the application of an external stimulus. Their major drawback is their low stiffness compared to smart ...
Polyurethane/Acrylate Hybrids: Effects of the Acrylic Content and Thermal Treatment on the Polymer Properties
(John Wiley & Sons IncHobokenEUA, 2010)
Effect of the hard segment chemistry and structure on the thermal and mechanical properties of novel biomedical segmented poly(esterurethanes)
(Springer, 2008-08)
Two series of biomedical segmented polyurethanes (SPU) based on poly(ε-caprolactone) diol (PCL diol), 1,6-hexamethylene diisocyanate (HDI) or L-lysine methyl ester diisocyanate (LDI) and three novel chain extenders, ...
Synthesis, characterization and applications of amphiphilic elastomeric polyurethane networks in drug delivery
(Soc Polymer Science Japan, 2012-07-04)
Polyurethanes have a key role in the development of many different biomedical devices because of their exceptional biocompatibility, mechanical properties and versatility. Although linear segmented polyurethanes have been ...
Síntese e caracterização de Poli(L-co-DL ácido lático-co-policaprolactona)uretana.
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2018-03-27)
Polyurethanes are applied for many purposes. This wide use is due to the versatility of these polymers, consisting of flexible and rigid segments, whose combination determines their characteristics. Therefore, the main ...
