Dispersing nanoparticles in a polymer matrix is intrinsically challenging due to unfavorable entropic interactions between the matrix and the nanoparticle. In this research dispersion of nanoparticles in polymer matrix was studied and the effect of dispersion on properties was investigated. The properties of polymer composite depend on the type, size, shape, concentration of nanoparticles, and ...

We have proposed composite films composed of a molecular-aligned polymer and liquid crystal (LC) for substrate-free liquid crystal displays with high-contrast images. We successfully controlled the molecular alignment of the LC and formed molecular-aligned LC droplets in the polymer by controlling the fluidity of the LC/monomer mixture and the curing rate of the monomer. key words: substrate-fr...

A composite polymer surface coated on a tin oxide offers dramatic improvement in the stability and sensitivity of voltammetric measurement of pyridostigmine bromide as compared to individual tin oxide, polyaniline or polypyrrole coated electrode. A linear current response was achieved with a detection limit of 1x10 M. The stability and morphology of the polymer surfaces were determined by therm...

Using an environmentally friendly and inexpensive method, AuNPs gold nanoparticles (AuNPs) were prepared using pulsed laser ablation technique (PLAL) 600,700mJ different energies of a target immersed distilled water (DW). The size shape the verified by examining morphological characteristics, as they showed value diameters between 30-75 nanometers with almost regular spherical shapes. Solution ...

Abstract Block polymer structure-directing agents (SDA) enable the production of porous nanoscale materials. Most strategies rely upon equilibration where diverse morphologies are realized in functional This review details how solvent selectivity determines SDA behaviors, spanning from bulk-type to solution-type. Equilibrating behavior either type, however, obscures nanostructure cause-and-effe...

The poly(methyl methacrylate) (PMMA)/poly(methyl methacrylate)–poly(methyl acrylate acid) copolymer (PMMA–PMAA) composite polymer latex were synthesized by the method of soapless seeded emulsion polymerization. The morphology of the composite polymer latex was core–shell structure. The core was PMMA and shell was PMMA–PMAA copolymer. Because the PMMA–PMAA copolymer was shell, the carboxylic aci...

Bio-inspired Laponite (clay)-liquid crystal (LC) polymer composite materials with high clay fractions (>80%) and a high level of orientation of the clay platelets, i.e. with structural features similar to the ones found in natural nacre, have been shown to exhibit a promising behavior in the context of reduced oxygen transmission. Key characteristics of these bio-inspired composite materials ar...

Abstract Three-dimensional (3D) printing technology is an additive manufacturing designed to rapidly process and manufacture complex geometrical components based on computer model design. Based a 3D data model, materials are accumulated layer by through control, the finally turned into stereoscopic object. Compared with traditional methods, has advantages of saving man-hours, easy operation, no...

Polymer composites consisted of small hydrophilic pockets homogeneously dispersed in a hydrophobic polymer matrix are important in many applications where controlled release of the functional agent from the hydrophilic phase is needed. As an example, a release of biomolecules or drugs from therapeutic formulations or release of salt in anti-icing application can be mentioned. Here, we report a ...
