Nano clay and itrsquos applications
ByThikra Kadhim Ibrahim
ClayClay is a naturally occurring material composedprimarily of fine grained minerals which showsplasticity through a variable range of watercontent and which can be hardened when driedor fired Clay deposits are mostly composed ofclay minerals (phyllosilicate minerals) andvariable amount of water trapped in the mineralClay materials have been investigated because oftheir importance in agriculture in ceramics inconstruction and other uses

GROUPS OF CLAYS
Nano-clayNano clays are minerals which have a high aspect ratio
and with at least one dimension of the particle in thenanometer range The purity and cationexchange capacity of the nano-clay are also criticalcharacteristics The purity is important in achievingmaximum increases in mechanical properties andachieving optimum clarity for use in films Impuritiesact as stress concentrators resulting in poor impactand tensile properties The cation exchange capacityprovides the surface activity necessary for acceptanceof modifiers or surface treatments

APPLICATION OF NANOCLAY
1Nanoclay is used in the ink formulation It helps toadjust the consistency of printing inks to the desiredvalue avoiding pigment sedimentation providinggood colour distribution obtaining desired filmthickness etc by incorporation of small amount oforganically modified layered silicate
2Thickening lubricating oils with nanoclays canproduce especially high temperature resistantlubricating greases
3The performance of cosmetics is enhancedby the use of nanoclays and they allow goodcolour retention and coverage for naillacquers lipsticks and eye shadows
Fields of application (paints inks greases and cosmetics)
4Waste water treatment
The use of nanoclays in wastewater treatment has becomecommon in industry today Nanoclays exhibit a synergisticeffect with many commonly utilized water treatment unitprocesses including granular-activated charcoal reverseosmosis and air strippers Granular-activated carbon isparticularly effective at removing a large range of organicmolecules from water however is very poor for removinglarge molecules such as humic acid and wastewaterscontaining emulsified oil and grease Nanoclays have provento be the technology of choice for treating oily wastewaters
5Nanoclay as drug vehicle nanoclays as drugvehicle for controlled release of drug is oneof the born age area in medicinalapplication nanoclays have great potentialas compared to polymer and carbonnanotubes for drug delivery
