Nano-adsorbents control surface properties of polyurethane

A closed-form, hierarchical, multi-interphase model for composites—Derivation, verification and application to nanocomposites

“…Evidence shows that the thickness and material properties of the interphase region are mainly determined by the chemical and physical characteristics and interactions of the inclusion and the matrix (Smith et al, 2002;Liu et al, 2004;Lyu. et al, 2007).…”

“…m(m Z0) is a material parameter depending on the temperature and the chemical environment of the composite. There are different approaches to determine t 0 (Smith et al, 2002;Liu et al, 2004;Lyu. et al, 2007;Li et al, 2008aLi et al, , 2008b.…”

Biomaterials based on new polyurethane and hydrolyzed collagen, k-elastin, hyaluronic acid and chondroitin sulfate

“…They are used as encapsulants for hollow-fiber devices, dipmolded gloves and balloons, asymmetric membranes, functional coatings, and as extruded profiles for catheters. Bio-and haemocompatibility, stability, appropriate mechanical properties and other conditions can be satisfied by the appropriate selection of polyurethanes composition [7,8] or by blending with other polymers.…”
