Poly(3-hydroxybutirate) (PHB) is a bacterial polyester, which shows a high potential as a material for biotechnology and medicine, including drug delivery and production of biodegradable implants. Being a semicrystalline polymer, PHB is able to form [...]
Micromechanical Analysis of Polypropylene-Nanofiber Composites
Locker C.R., Bergstrom J., Liu X., Tsou A.H., Buchholz V.B., Mehta A.K., ExxonMobil Research and Engineering, US
Nanofiber-reinforced polymer-based compounds have the potential to be the next generation light-weight structural plastic materials. In this work, micromechanical models of polymer-nanofiber and polymer-rubber-nanofiber systems have been developed to compute the thermal, mechanical, and thermo-mechanical [...]
Multifunctional Nanocomposites: Modeling and Characterization
Unlike traditional adhesive bonds, where only one material property is enhanced, multifunctional systems are capable of fulfilling several design requirements (e.g., strength/toughness, sensing, actuation, and condition monitoring). In this research, we intend to introduce this [...]
Computer Modeling Of Star Polymer Molecules With Diblock Arms
Using molecular dynamics simulations and supercomputers we have studied a number of star polymer molecules in an aqueous environment to help determine how their composition affects structure, thermodynamic stability and kinetics. We have examined stars [...]
Plasmonic nanoparticles ordered in self-assembled materials
Tallet C., Vieaud J., Merchiers O., Sivasankaran P.C., Nallet F., Aradian A., Ponsinet V., Centre de Recherche Paul Pascal, FR
Bottom-up approaches, and among them nanochemistry and self-assembly, have recently appeared as promising tools for the fabrication of plasmonic nanostructured materials. We study nanocomposites of polymers and gold nanoparticles presenting plasmonic resonance at a visible [...]
Optical Properties of Hybrid Materials
Optical properties of materials are very important for many applications. One example is optical computing where photons replace electrons so that the computation speed can be further improved. In construction of optical computing devices, polymers [...]
Nanostructured Stearic Acid for Gas sensing applications
In this paper we report the fabrication of long chain polymer molecule Stearic Acid by physical vapor deposition method. Thin films of stearic acid are characterized by X-ray diffraction for the crystalline quality and by [...]
Effect of Carbon Black and Silver Nanoparticle Loading on the Structural and Thermo-Mechanical Properties of Chitosan-Based Films
This work addresses the synthesis and structural and thermo-mechanical characterization of bare and chitosan-based nanocomposite films synthesized via spin coating and sol casting techniques. The dependence of these properties as a function of the nature [...]
Electrosynthesis of Intrinsically Conducting Polymers/Silicon Nanocomposites: Formation Mechanism and Optical Properties
When a silicon wafer is subjected to electrochemical etching in fluoride-based solution, silicon surface develops pores, often called porous silicon (PSi). A variety of pore sizes ranging from a few nanometers up to a few [...]
Polymer Nanomanufacturing Strategies for Multifunctional Nanomaterials
Polymeric materials offer tremendous potential for preparing functional materials using nanoscale fillers and features. For example, the use of nanolayered materials in barrier or optical applications, nanofeatured materials for hydrophobic surfaces, and patterned polymer blends [...]
Synthesis, characterization and viscoelastic properties of Nanocrystalline Cellulose grafted with Poly(N-isopropylacrylamide)
Hemraz U.D., Danumah C., Lu A., Boluk Y., National Institute for Nanotechnology, University of Alberta, CA
Nanocrystalline cellulose (NCC) is a renewable, nontoxic and biodegradable nanomaterial that can be obtained by acid hydrolysis of the amorphous regions of the widely available cellulose. The relative low density, low cost, high aspect ratios, [...]
Stimuli-responsive nanogels by e-beam irradiation of dilute aqueous micellar solutions: Nanogels with pH controlled LCST
Nanogels have attracted growing interest owing to their potential for applications in drug delivery systems. In this work, responsive nanogels based on amphiphilic block copolymers crosslinked in the micellar state were prepared by electron beam [...]
