Low Permeability Biomedical Polyurethane Nanocomposites for Cardiac Assist Devices
Introduction Biomedical polyurethanes generally possess good biocompatibility and mechanical properties but, due to the low Tg and relatively high concentration of soft segments, are relatively permeable to air and water vapor. The ‘traditional’ approach to the permeability problem is to modify the chemistry of the copolymer, particularly that of the soft segment. For example, replacement of po...
متن کاملReview Polyurethane Nanocomposites
This review describes the present state of science and technology of photopolymerizable (UV-curable) polyurethane (PU) nanocomposites which include nanosilica and organically-modified clay (organoclay). A number of documented improvements of properties of PU nanocomposites compared to the pristine PU are presented. Many data on the structure and properties of PU nanocomposites were obtained not...
متن کاملPolyurethane Organosilicate Nanocomposites as Blood Compatible Coatings
Polymer clay nanocomposites (NCs) show remarkable potential in the field of drug delivery due to their enhanced barrier properties. It is hypothesised that well dispersed clay particles within the polymer matrix create a tortuous pathway for diffusing therapeutic molecules, thereby resulting in more sustained release of the drug. As coatings for medical devices, these materials can simultaneous...
متن کاملNew polyurethane nanocomposites based on soya oil.
New polyurethane (PU) nanocomposites were prepared from a dispersion of 0 - 5% montmorillonite (MMT) clay with isocyanate and soya oil polyol that was synthesized via transesterification of triglycerides to reduce petroleum dependence. FT-IR spectra indicate the presence of hydrogen bonding between nanoclay and the polymer matrix, whereas the exfoliated structure of clay layers was confirmed by...
متن کاملNonisocyanate based polyurethane/silica nanocomposites and their coating performance
A series of silica nano-particles with different size were prepared by sol–gel technique, then surface modification by using cyclic carbonate functional organoalkoxysilane (CPS) was performed. Various amounts of carbonated silica particles directly added into carbonated soybean oil (CSBO) and carbonated polypropylene glycol (CPPG) resin mixture to prepare polyurethane–silica nanocomposite coati...
