abric materials have a wide diversity in the nature which can highlight cotton as one of the most abundant consisted in
96% of cellulose. The functionalization of cotton avoids facile degradation and damage by the environment, moisture,
microorganisms, etc., and allows obtaining a highly desired material with extensile applications such as medical, construction,
textile, among others. Electrostatic assembly better known as layer-by-layer (LbL) technique is an alternative option of cotton
modification that consists in depositing controllable nano layers by the adsorption of oppositely charged poly electrolytes on the
surface for further immobilization of charged nanoparticles, besides, LbL technique is very attractive for cotton modification
due to its simplicity and its easy incorporation in just one coating at ambient conditions. LbL has an environmental characteristic
that the most common solvent employed is water and the concentration needed is relatively low. Nanostructured materials
have been aimed of many investigations in the textile field because of their attracting characteristics such as high surface area
and unique physicochemical properties compared to bulk materials. Recently, core-shell nanoparticles have been focused due
to their synergistic affects using a combination of a core and a shell made by different precursors and which unique and useful
functionalities are obtained depending on this interaction affording to expand the fields of applications according to the shape,
size and smart characteristics given by these core-shell nanostructures. In the present study, we have pre-treated and modified
cotton fibers using PDDA and PSS polymers in order to functionalize the surface with charged polyelectrolytes for further
nanoparticles attaching by electrostatic interaction. Magnetite and magnetic core-shell mesoporous suspension were prepared
for coating the cotton fibers to compare and characterize the resulting material as a novel, innovative and promising product
for different fields of application.
