Polysaccharide - Modified MMT/ Modified MMT/ Polysaccharide – MNP, Lignin - Modified MMT Nanocomposites Verses Polyethyleneimineimine- Modified MMT-: A Comparative Analysis of Sustained Pesticide Delivery

The substance properties can change drastically at the nanoscale. Materials can demonstrate new properties with just a reduction in size and no alteration in the substance itself. In this paper, modified montmorillonite (M MMT) and a variety of different hybrid natural-based nanocomposites were systematically investigated by combining a suspension of (M MMT) as a nanofiller with polymers comprising either chitosan (CS), starch (S), β-cyclodextrin (β-CD), polyethyleneimine (PEI), while in other cases polysaccharides such as chitosan (CS), carboxymethyl-β-cyclodextrin (CM-β-CD) served as the macroscopic polymer matrix while magnetite (MNP) constituted the nanoparticles thereby resulting in the polysaccharide-MNP nanocomposite. In the third case, the macroscopic polymer matrix of lignin mixed with M MMT suspension as nanofiller was analysed as controlled release formulations and the efficiencies of PLE and SPR for chlorpyrifos (ChP) pesticides were compared with gas chromatography mass spectrometry (GC-MS) and corrected with inductively coupled plasma mass spectrometry (ICP MS).
