A kind of spin crossover-macromolecule polymer composite material, [Fe(NH(2)trz)(3)(ClO(4))(2)]-PVP (NH(2)trz is 4-amino-1,2,4-triazole and PVP is polyvinylpyrrolidone), appears as homogeneous film with a regular structure in nano-scale and shows the spin crossover (SC) phenomenon.
This study presents the fabrication process and display characteristics of a flexible organic polymer display device that consists of a thin substrate of Polyether Sulfone, a multilayer serpentine-type microheater array that is fabricated on the substrate, and a UV-sensitive polydiacetylene (PDA)-polyvinyl alcohol (PVA) composite film. A retention time of one second is achieved with cell sizes ...

Submitted for the MAR09 Meeting of The American Physical Society Mechanics of nanoscale composite films from stress-electrical measurements: A nanoscale foam CHIEU NGUYEN, VIVEK MAHESHWARI, RAVI SARAF, CHEMICAL ENGINEERING-UNIVERSITY OF NEBRASKALINCOLN TEAM — Nanometer thin (> 100nm) composite films consisting of polymers and organic-inorganic materials such as nanoparticles, quantum dots, nano...
Nowadays, there is a growing interest to develop biodegradable functional composite materials for food packaging and biomedicine applications from renewable sources. Some composite films were prepared by the casting method using chitosan (CS) and agarose (AG) in different mass ratios. The composite films were analyzed for physical-chemical-mechanical properties including tensile strength (TS), ...
An anisotropic biocompatible composite PCL-PTFE film was used to guide smooth muscle cell outgrowth along defined directions.
Fabrication of biocompatible and mechanically reinforced graphene oxide-chitosan nanocomposite films
BACKGROUND Graphene oxide (GO)can be dispersed through functionalization, or chemically converted to make different graphene-based nanocomposites with excellent mechanical and thermal properties. Chitosan, a partially deacetylated derivative of chitin, is extensively used for food packaging, biosensors, water treatment, and drug delivery. GO can be evenly dispersed in chitosan matrix through th...
In this article, we propose a simple scheme to make a metallic film on a semi-infinite substrate optically transparent, thus obtaining a completely transparent electrode in a desired frequency range. By placing a composite layer consisting of dielectric and metallic stripes on top of the metallic one, we found that the back-scattering from the metallic film can be almost perfectly canceled by t...
Surface nanomechanical behavior under nanoindentation of ZrN and ZrCN film on NiTi substrate was studied. The surface hardness and modulus of the films increase initially with larger nanoindentation depths and then reach their maximum values. Afterwards, they diminish gradually and finally reaching plateau values which are the composite modulus and composite hardness derived from the ZrN/ZrCN f...
