The present research aims at synthesizing micro-porous and fluorescent polymer by microwave assisted synthesis allowing to reduce preparation time of 3 days at 180 °C using conventional method.
The aim of this work is to study the rheological and mechanical properties of Poly(lactic acid) and High density polyethylene and blends (PLA/HDPE) in the molten state with recpect to shear stress, temperature and blends compositions using brabender mixer.
In this study, several samples of a common polymer (aniline-phenolformaldehyde) we prepared by condensation polymerization method based on aniline, phenol, formaldehyde and in the presence of a catalyst of ammonia solution at different concentrations.
Photonic crystals is a low-loss periodic medium with periodic changes of refractive index, which is used to control the light. Theoretically, Photonic crystals can be studied using Maxwell equations, but it’s difficult to find a general analytical solution for these equations, since we are dealing with vectors. So we resort to the numerical solutions for Maxwell’s equations to calculate the reflection and transmission coefficients and the Photonic band gap.
