Skeletally Modified Polyamide Flame Retardant Coatings

J. Sheeba Vinolia, D. Duraibabu, S. Aparna, S. Ananda Kumar
The use of polyamide coatings for electrical applications is restricted mainly because of its inadequate flame retardant behaviour. In order to improve its flame retardant behaviour, polyamide is modified by incorporating phosphorus moiety in its backbone. The structure of the phosphorus and poly amide was confirmed by infrared spectroscopy (FT-IR), NMR, thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC), UL-94 vertical burning tests and char residue tests. From the resul...

Preparation of Poly Aniline by Chemical Ox-idative Method and Its Characterization

Tassew Alemayehu, Diribe Abiebie

The present work reports the oxidative synthesis of poly aniline using K2Cr2O7 as an oxidizing agent and H2SO4 as dopant. The synthesized polymer was characterized by solubility test and UV- visible spectroscopic technique. The synthesized polymer (poly aniline) was insoluble in ethanol, acetone, benzene and water. The absorbance of UV-visible spectra shows two reductive peaks at some wake length. The band ob

Preparation of PANI-PVA Composite Film with High Conductivity

Xiaohua Wang

The PANI-PVA composite films adopting PVA as the base material and doped with hydrochloride, DBSA, amino sulfonic acid aqueous solution were prepared and their conductivity was compared. Among these PANI-PVA composite films, the conductivity of HCl-PANI-PVA film is the highest. At the same time, the influences of mass ratio between PANI and PVA, acid content, oxidant content, reaction time and drying temperature of film on the conductivity of HCl-PANI-PVA film we

Non-Linear Optical Properties of Substituted Hexatriene: AM1 and ab Initio Quantum Chemical Calculations

Nouar Sofiane Labidi

We report ab initio studies of the dipole polarizabilities (α) and first static hyperpolarizabilities (β) for a set of substituted hexatriene in which electron donating (D) and electron accepting (A) groups were introduced either end parts of the hexatriene chain NO2-(CH=CH)3-D. Geometries of all molecules were optimized at the Hartree-Fock HF/6-311 G(2d,p) level of theory. Polarizabilities of these molecules w

Estimation of Trace Elements in Fly Ash Released from Coal Combustion

Ali A. Eltayeib

Qingshan Thermoelectric Plant located in Wuhan City, Hubei Province, China, and it uses coal as a fuel. Coal combustion generates not only gaseous pollutants like SO2 and NOx but also toxic and heavy metals to the atmosphere. From the environmental point of view, the determination and speciation of trace toxic and heavy metals released from coal combustion are very important. In this work, the atomic spectroscopic methods for determination of so
