What is carbon nanotube functionalization?
The non-covalent functionalization is an alternative method for tuning the interfacial properties of nanotubes. The CNTs are functionalized non-covalently by aromatic compounds, surfactants, and polymers, employing π – π stacking or hydrophobic interactions for the most part.
What do you mean by functionalization?
Functionalization is the process of adding new functions, features, capabilities, or properties to a material by changing the surface chemistry of the material. It is a fundamental technique used throughout chemistry, materials science, biological engineering, textile engineering, and nanotechnology.
What is non-covalent functionalization?
The purpose of non-covalent functionalization is to enhance the bio-affinity of CNTs as well as to establish effective electrical communication between the bioreceptor and the transducer in biosensor platforms, that will contribute to signal amplification and transduction.
What are carbon nanotubes and their properties?
Carbon Nanotubes Properties CNTs have high thermal conductivity. CNTs have high electrical conductivity. CNTs aspect ratio. CNTs are very elastic ~18% elongation to failure. CNTs have very high tensile strength.
Why functionalization is important?
Functionalization enhances the properties and characteristics of nanoparticles through surface modification, and enables them to play a major role in the field of medicine.
Is functionalization a word?
noun. 1The process or action of making something functional; the process of acquiring a particular function.
What is functionalization in chemistry?
Functionalization refers to the addition of functional groups to a compound by chemical synthesis. In materials science, functionalization is employed to achieve desired surface properties; functional groups can also be used to covalently link functional molecules to the surfaces of chemical devices.
Why is surface functionalization?
Surface functionalization is an effective and often simpler way of altering the surface properties of a material or device to achieve specific goals such as inducing a desired bioresponse or inhibiting a potentially adverse reaction.
What is difference between single walled and multiwalled nanotubes?
Single-walled carbon nanotubes are composed of a single layer of graphene which forms a cylindrical shape. Multi-walled carbon nanotubes made of multiple layers of graphene, which formed in a concentric pattern around the smallest nanotube.
