Why polymer nanocomposites are unique?
Polymer nanocomposites have advantages: (1) they are lighter than conventional composites because high degrees of stiffness and strength are realized with far less high-density material, (2) their barrier properties are improved compared with the neat polymer, (3) their mechanical and thermal properties are potentially …
What are polyamino acids?
Polyamino acids are polymerized from single amino acid that has molecular mass and polydispersity as similar as polysaccharides. Polyamino acid biosynthesis is considered to be an interesting example of biopolymer synthesis that is being produced by fermentation process.
What is nano filler?
One-dimensional (1D) nanofillers are those fillers that have one of their dimensions less than 100 nm [19]. They are usually in the form of sheets of one to a few nanometers thick to hundreds and thousands of nanometers long. Montmorillonite clay and nanographene platelets are common examples of 1D nanofillers.
What are nanocomposites examples?
Nanoparticles such as graphene, carbon nanotubes, molybdenum disulfide and tungsten disulfide are being used as reinforcing agents to fabricate mechanically strong biodegradable polymeric nanocomposites for bone tissue engineering applications.
What are polymer nanocomposites made of?
A polymer nanocomposite is a composite material comprising a polymer matrix and an inorganic dispersive phase that has least one dimension that is nanometric in scale.
Is polyamino an amino acid?
A polyamino acid, sometimes also called polypeptide, is a synthetic biopolymer made from amino acid repeating units, i.e. -[NH-CHR-CO]x-.
Where are nanocomposites used?
A range of polymeric nanocomposites are used for biomedical applications such as tissue engineering, drug delivery, cellular therapies. Due to unique interactions between polymer and nanoparticles, a range of property combinations can be engineered to mimic native tissue structure and properties.
