This Communication describes the fabrication of planar structures comprising metallic features with nanometer-scale lateral dimensions in polymer prepared by sectioning a thin metallic film, embedded in a polymer matrix, in a plane perpendicular to the metallic film. This procedure converts a structure that is thin along the z-axis into a structure that is thin along the x-axis. The embedded th...

Optically active bionanocomposite membranes composed of polyester(PE) and cellulose /silica bionanocomposite (BNCs) are a novel method to enhance gas separation performance. Commercially available silica nanoparticles were modified with biodegradable nanocellulose through ultrasonic irradiation technique. Transmission electron microscopy (TEM) analyses showed that the cellulose/silica composite...

We study associating polymer gels under steady shear using Brownian dynamics simulation to explore the interplay between the network structure, dynamics, and rheology. For a wide range of flow rates, we observe the formation of shear bands with a pronounced difference in shear rate, concentration, and structure. A striking increase in the polymer pressure in the gradient direction with shear, a...

Using Electrostatic Spray Coating Technique, Polypropylene Powder (EPD 60R) was applied on carbon steel substrates at room temperature. In order to obtain a uniform coating, steel substrates with powder coatings were heated in a vacuum oven at various temperatures up to 250° C for various periods of time up to 45 min and a pressure of 200 mb. The coatings produced had thicknesses of around 470 ...

Miniemulsion polymerization is one of heterogeneous polymerization method that can be effectively used to synthesis of various novel organic-inorganic nanocomposite particles. This method can provide opportunity of good incorporation between the polymer and inorganic phases in the formed submicrometer-sized particles. In this article, we report preparation polystyrene/silica nanocomposite p...
