Abstract
Anionic layered Mg-Al Layered Double Hydroxides (LDHs) have the potential to develop a broad range of new polymer nanocomposites with improved properties viz flame-retardancy (FR), retention or stabilization of dyes, additives, etc. New Low density polyethylene (LLDPE) based nonocomposite materials containing Mg-Al LDH and biocides (BIT) have been designed, synthesized and characterized. MAH-g-PE is used as a compatibilizer. Modification of LDH changes interlayer spacings (distance). Thermogravimetry analysis (TGA) depicted that the loss of biocides due to diffusion/ evaporation is clearly reduced by LDH. Scanning transmission electron microscopy (STEM) images of diluted samples show that most LDH still consist of several layers indicating incomplete or little e xfoliation.
