Hemocompatibility of Chitosan/poly(acrylic acid) Grafted Polyurethane Tubing.
The activation and adhesion of platelets or whole blood exposed to chitosan (CH) grafted surfaces is used to evaluate the hemocompatibility of biomaterials. The biomaterial surfaces are polyurethane (PU) tubes grafted with an inner poly(acrylic acid) (PAA) and an outer CH or quaternary ammonium modified CH (CH-Q) brush. The CH, CH-Q and PAA grafted layers were characterized by ellipsometry and ...
متن کاملDevelopment of Styrene-Grafted Polyurethane by Radiation-Based Techniques
Polyurethane (PU) is the fifth most common polymer in the general consumer market, following Polypropylene (PP), Polyethylene (PE), Polyvinyl chloride (PVC), and Polystyrene (PS), and the most common polymer for thermosetting resins. In particular, polyurethane has excellent hardness and heat resistance, is a widely used material for electronic products and automotive parts, and can be used to ...
متن کاملThermal Conductivity and Interconnectivity of Hexamethylene Diisocyanate Contained Polyurethane Grafted Multiwall Carbon Nanotube/Polyurethane Nanocomposite Film
The hexamethylene diisocyanate (HDI) contained polyurethane (PU) grafted multi-walled carbon nanotubes (HDI-g-MWNTs) have been synthesized by simple blending method to fabricate thermal conductive nanocomposite. This method shows that HDI-g-MWNTs can improve the interfacial compatibility between HDI-g-MWNTs and matrix. The HDI base PU thermal conductive film (HDI-PU) showed enhanced dispersibil...
متن کاملHemocompatibility of Inorganic Physical Vapor Deposition (PVD) Coatings on Thermoplastic Polyurethane Polymers
Biocompatibility improvements for blood contacting materials are of increasing interest for implanted devices and interventional tools. The current study focuses on inorganic (titanium, titanium nitride, titanium oxide) as well as diamond-like carbon (DLC) coating materials on polymer surfaces (thermoplastic polyurethane), deposited by magnetron sputtering und pulsed laser deposition at room te...
متن کاملDiffusion of phthalic acid esters from PVC milk tubing.
At the beginning of our work on diffusion processes in PVC tubing used in milk collection it was observed that plastic tubes which have been used for extended periods lose their originally smooth inner surface (1). In spite of careful maintenance, fine tears arise, forming a network on the inside which is in contact with milk, water, and cleaning solution (Fig. 1).
