  Flammability and thermal properties of novel semi aromatic polyamide/organoclay nanocomposite

  摘要：

  The development of semi aromatic polyamide/organoclays nanocomposites (PANC) is reported in this communication. New polyamide (PA) was successfully synthesized through direct polycondensation reaction between bio-based diacid and aromatic diamine. PA exhibited strong UV vis absorption band at 412 nm. Its photoluminescence spectrum showed maximum band at 511 nm in the green region. The surface modification of montmorillonite was carried out through ion-exchange reaction using 1,4-bis[4-aminophenoxy]butane (APB) as a modifier. Then PANCs containing 3 and 6 wt.% of the modified montmorillonite (MMT-APB) were prepared. Flammability and thermal properties of PA and the nanocomposites were studied by microscale combustion calorimeter (MCC), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). TGA results in both air and nitrogen atmospheres indicated improving in thermal properties of PANCs compared to the neat PA. According to MCC analysis, a 31.6% reduction in pHRR value has been achieved by introducing 6 wt.% of the organoclay in PA matrix. (C) 2014 Elsevier B.V. All rights reserved.

  日期：2015.5

  An efficient and green synthesis of 2,4,6‐triarylpyridines by a one‐pot three‐component condensation of aromatic aldehydes, substituted acetophenones, and ammonium acetate without catalyst at 130°C under solvent‐free conditions is described. This method offers several advantages such as simple procedure, easy work‐up, short reaction time, low cost, environmentally friendly conditions, and moderate to high yields.
