Nanomaterials have structural features in between those of atoms and the bulk materials. However, the dimensions of nanometer properties are significantly different from those of atoms and bulk materials. The nanometer size of materials mainly gives them larger surface area, higher surface energy, spatial blockage and more minor imperfections, which are not present in the corresponding aggregate materials.
The surface properties of nanoparticles are the main criteria for applications. Therefore, the following devices are used to analyse the nanoparticle with high resolution.
- Scanning Electron Microscope (SEM)
- Tunnelling Electron Microscope (TEM)
- Atomic Force Microscope (AFM)
Applications of Nanochemistry:
The range of retail products available today is comprehensive, including stain-resistant and wrinkle-free textiles, cosmetics, sunscreens, electronics, paints and varnishes. Nanochemistry is applied in all these substances. Some of them are given below.
Application of nanochemistry
- Metallic nanoparticles have the potential to be very active catalysts.
- Nanocoatings and nanocomposites are used to manufacture various products, including sports equipment, bicycles, and automobiles.
- Nanotechnology is used in the creation of synthetic skin as well as implant surgery.
- Nanomaterials that conduct electricity are used as minute conductors in electronics to create circuits for microchips.
- Nanomaterials are widely used in the manufacture of cosmetics, deodorants, and sunscreen lotions.
- Fabrics contain nanoparticle substances that inhibit the growth of bacteria.
- Nanochemistry is used in the manufacture of space, defence, and aeronautical devices.
Drawbacks of Nanomaterials in chemistry:
- Nanoparticles are uncertain when they react with oxygen.
- Their exothermic combustion with oxygen can readily make an explosion.
- As nanoparticles are very reactive, they naturally combine with impurities as well.
- Nanomaterials are biologically harmful and toxic.
- It is a challenge to synthesise, isolate and apply them.
- There are no hard-and-fast safe disposal policies for nanomaterials.
