In this study, we sought to develop strategies for improved endothelialization of a new polymer coating for vascular stents. Surface enhancement of the new poly-1,8-octanediol-co-citric acid (POC) polymer was achieved through conjugation of anti-CD34 antibody and incorporation of vascular endothelial growth factor and basic fibroblast growth factor-containing poly-lactic-co-glycolic acid microp...

A blue reflective photonic polymer coating which can be patterned in full color, from blue to red, by printing with an aqueous calcium nitrate solution has been fabricated. Color change in the cholesteric liquid-crystalline polymer network over the entire visible spectrum is obtained by the use of nonreactive mesogen. The pattern in the coating is hidden in the blue color dry state and appears ...

The realization of a complete tandem polymer solar cell under ambient conditions using only printing and coating methods on a flexible substrate comprises a fully scalable

Channel waveguides based on a polymer, 6-fluorinated-dianhydride/epoxy, which is actively doped with a Nd complex, Nd(thenoyltrifluoroacetone)(3) 1,10-phenanthroline, are fabricated by a simple and reproducible procedure, spin coating a photodefinable cladding polymer onto a thermally oxidized silicon wafer, photopatterning, backfilling with the active core polymer, and spin coating with an upp...

Vertical carbon nanotube (CNT) forests bonded at room temperature with sprayed on nanoscale polymer coatings are found by measurement to produce thermal resistances that are on a par with those of conventional metallic solders. These results are achieved by reducing the high contact resistance at CNT tips, which has hindered the development of high performance thermal interface materials based ...

Due to its bioactivity, hydroxyapatite (HAp) is one of the most perspective materials for controlled drug delivery. Biodegradable polymers like chitosan and sodium alginate are used as coating materials for ceramic scaffolds. In this work the application of HAp/sodium alginate or chitosan composite materials which provide controlled lidocaine release is discussed. The polymers and lidocaine hyd...

In this work we present a novel route to produce a graphene-based film on a polymer substrate. A transparent graphite colloidal suspension was applied to a slat of poly(methyl methacrylate) (PMMA). The good adhesion to the PMMA surface, combined with the shear stress, allows a uniform and continuous spreading of the graphite nanocrystals, resulting in a very uniform graphene multilayer coating ...

A thermo-sensitive imprinted polymer coating CdTe quantum dots was developed to prepare fluorescent thermo-sensitive protein-affinity materials, which exhibited high specific recognition ability towards target proteins.

In the filling of polymer, coal fly ash has been limited in use by its unlovely grey color. In order to improve the qualities of coal fly ash from Huaneng Power international Incorporation Dezhou Power Plant, its meso-structure and influencing factors on whiteness have been tested and analyzed. Ca(OH)2-H2O-CO2 system to modify the fly ash is conducted. Round coating testify that the system can ...
