In polymer chemistry, in situ polymerization is a preparation method that occurs "in the polymerization mixture" and is used to develop polymer nanocomposites from nanoparticles. There are numerous unstable oligomers ( molecules ) which must be synthesized in situ (i.e. in the reaction mixture but cannot be isolated on their own) for use in ...
The template method to be described in the following has the advantage such that it allows the preparation of nanotubes and nanorods with very high precision. The method is based on the use of well defined porous templates, such as porous aluminum or silicon. The basic concept of this method is to exploit wetting processes. A polymer melt or ...
The top-down approach is breaking down of a system into small components, while bottom-up is assembling sub-systems into larger system. [15] A bottom-up approach for nano-assembly is a primary research target for nano-fabrication because top down synthesis is expensive (requiring external work) and is not selective on very small length scales, but is currently the primary mode of industrial ...
Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...
The Stöber process is a well-studied example of polymerization of an alkoxide, specifically TEOS. The chemical formula for TEOS is given by Si(OC 2 H 5) 4, or Si(OR) 4, where the alkyl group R = C 2 H 5. Alkoxides are ideal chemical precursors for sol–gel synthesis
Given that natural and synthetic polymers are defined by their own set of advantages and disadvantages, an ongoing area of research aims to create composite hydrogels for nanogel synthesis that combines synthetic and natural polymers to leverage the benefits of both in one nanogel formulation. [3]
Synthetic chemical methods can be used to create synthetic molecular motors, such as in a so-called nanocar. Biomimetic approaches Bionics or biomimicry seeks to apply biological methods and systems found in nature to the study and design of engineering systems and modern technology.
