The paper presents result of experimental measurements of viscoelastic properties of agarose gel after sonication and with silver nanoparticles doped. Researches were conducted using a HAAKE MARS 2 rheometer (Thermo Electron Corporation, Karlsruhe, Germany), with serrated plate-plate measuring geometry. Viscoelastic properties of samples were measured with oscillation tests at constant deformation rate 0.1%, and frequency 1 Hz in the temperature range from 278 to 348 K. It was presented that using the sonication before solidification of gel results in increases of the storage modulus and complex viscosity of the solidified gel. It was also presented that when silver nanoparticles are doped into agarose gel, storage modulus and complex viscosity start to decrease at lower temperature.

A new kind of intermediate hybrid nanocomposites (NCs) composed of poly(amic acid) (PAA) and surface modified ceria nanoparticles (NP)s had been prepared by sonochemical assisted synthesis. The PAA containing pendent benzamide units had been synthesized by the reaction of 3,5‐diamino‐N‐(4‐hydroxyphenyl) benzamide and benzene‐1,2,4,5‐tetracarboxylic dianhydride through polycondensation reaction. The structure of the prepared PAA was studied by spectroscopic techniques. The surface modifications of ceria NPs were achieved by using hexadecyltrimethoxysilane. Results of FTIR analysis demonstrated that the aliphatic chains have been covalently bonded to the surface of the CeO2 NPs. PAA/CeO2 NCs with different contents including 4, 8, and 12 wt% of CeO2 NPs was prepared by using sonochemical method. Characterization with FTIR, powder X‐ray diffraction, field emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM) confirmed the success in synthesis of NCs with well dispersion properties. XRD analysis results showed that the obtained NCs displayed the crystalline nature of ceria NPs and the amorphous character of PAA matrix. The particles size of ceria NPs in NCs are about 50–70 nm as characterized by FE‐SEM, TEM, and AFM analyses. This work demonstrates the application of intermediates as new matrices for preparation of hybrid nanostructures. POLYM. ENG. SCI., 55:2339–2348, 2015. © 2015 Society of Plastics Engineers

“…The benefit of nanofillers is that they are miscible with the macromolecule matrix, utilizing inimitable synergisms between the combined materials. [16][17][18][19][20] These properties of macromolecules have had considerable developments owing to the incorporation of NPs. These properties are mechanical properties, e.g., strength, modulus and dimensional stability; decreased permeability to gases, water and hydrocarbons, thermal stability and heat distortion temperature, and optical clarity in comparison to conventionally filled polymers.…”

[16][17][18][19][20][21] Inorganic NPs, for instance, titanium dioxide (TiO 2 ) are inherently hydrophilic and in the case of utilizing them as filler, they are able to augment the hydrophilicity of the host macromolecule matrix. Furthermore, such additives, when they act as bonding (as hydrogen or covalent, i.e.…”

Poly(amide-imide)s (PAI)s as engineering materials have received more attention owing to their high thermal and chemical stability. Therefore, organic/ inorganic nanocomposite (NC) of these materials has been widely studied in the last few decades. Here, we present PAI-NCs preparation containing surface modified TiO 2 nanoparticles (NP)s by employing silane coupling agent under ultrasonic process. Optically active nanostructure PAI was prepared from 5-(2-benzimidazole)-1,3-phenylenediamine (4) and chiral diacid monomer N-trimellitylimido-L-leucine (5) using molten salt tetrabuthylammonium bromide as an activating medium. A considerable improvement of properties can be achieved by inserting NPs into the polymer matrix. The results of field emission scanning electron microscopy and transmission electron microscopy indicated that there is a little aggregation of a large quantity of particles. Thermogravimetric analysis confirmed that the heat stability of the polymer NCs in the temperature range of 400-800 ºC was enhanced.
