Comparison between polyurethanes containing castor oil (Soft Segment) and cancellous bone autograft in the treatment of segmental bone defect induced in rabbits
(2007-01-01)
The aim of this study is to compare polyurethanes containing castor oil (soft segment) in granular form compared to cancellous bone autograft applied to a segmental bone defect. Norfolk adult female rabbits - approximately ...

Effect of Nanotube Functionalization on the Properties of Single-Walled Carbon Nanotube/Polyurethane Composites
(John Wiley & Sons Inc, 2007-12)
A commercially available aliphatic thermoplastic polyurethane formulated with a methylene bis(cyclohexyl) diisocyanate hard segment and a poly(tetramethylene oxide) soft segment and chain-extended with 1,4-butanediol was ...
Influence of cellulose nanofibrils on soft and hard segments of polyurethane/cellulose nanocomposites and effect of humidity on their mechanical properties
(Elsevier B.V., 2014-12-01)
Cellulose nanofibrils (CNFs) were prepared by sulfuric acid hydrolysis from cotton microfibers, and used to prepare polyurethane (PU) nanocomposites by mixing CNFs and PU water suspensions. CNFs as nanofillers improved the ...
Polyurethane derived from Ricinus Communis as graft for bone defect treatments
(Assoc Brasil Polimeros, 2018-07-01)
This work evaluated polyurethane (Polyquil (R)) as a graft for treatment of bone defects. Bone defects of 1.5 x 0.5 cm were made in the calvaria of 16 rabbits. Eight animals had their defects treated with Polyurethane ...
Electrospun Nanofibrous Scaffolds Of Segmented Polyurethanes Based On Peg, Plla And Ptmc Blocks: Physico-chemical Properties And Morphology
(ELSEVIER SCIENCE BVAMSTERDAM, 2015)
Electrospun nanofibrous scaffolds of segmented polyurethanes based on PEG, PLLA and PTMC blocks: physico-chemical properties and morphology
(Elsevier Science, 2015-07-16)
Biocompatible polymeric scaffolds are crucial for successful tissue engineering. Biomedical segmented polyurethanes (SPUs) are an important and versatile class of polymers characterized by a broad spectrum of compositions, ...
Effect of the soft segment on the fatigue behavior of segmented polyurethanes
(Elsevier, 1999)
Effect of the soft-segment structure and molecular weight on the microphase separation in segmented polyurethanes (SPU) was determined by means of differential scanning calorimetry, small-angle X-ray scattering, dielectric ...
