Modified Graphene-Polymer Nanocomposites and Their Utilization in Various Applications
Özet
Graphene is a rising material in the field of materials science and condensed-matter physics. It indicates a two-dimensional material having high electronic and crystal property and has its own applications in new physics, which will be discussed briefly in this study, Graphene does not need any evidence highlighting its important in fundamental physics, unlike the case in the recognition of applications only when their material commercial products come into being. Generally, graphene, in terms of concept, is a new set of materials that is in the thickness of one atom that opens roads into physics that is low-dimensional. This new material, graphene, in the field of materials science, has, in the studies available, proved to be magnificent and amazing in providing a ground fertile for applications in different domains of sciences, such as (pharmaceutics, medicine, nanotechnology, and others).
For this study, modification of graphene was started with by some acids and bases to obtain acid- and amine-modified graphenes. Secondly, composites were prepared with acid- and amine-modified graphenes, and then their characterizations were made using different instrumental analysis methods such as FT-IR, XRD, SEM, Elemental analysis, TEM, Raman Spectroscopy, Mechanical test and DSC analysis.
Thirdly, modified-graphene nanocomposite film with 2-hydroxyethylcellulose (2-HEC) with and without doxorubicine (DOXO) (which is used for cancer therapy) was prepared for the purpose of drug delivery. Furthermore, to search the electrical properties of modified-graphene / 2-HEC nanocomposite films, with 4-point probe conductivity measurements were used.
