Abstract:A direct reaction with liquid bromine was used to prepare bromofullerene C 60 Br [14][15][16][17][18] . The brominated derivative reacted with previously prepared graphene-oxide (hereinafter GO), according to a method described by Hummer. The same method was used to oxidize graphite alone. The prepared graphite fullerene foil was brominated with liquid bromine and the graphene-oxide foil was reacted with bromofullerene. FT-IR analysis of all the obtained products was performed and also TGA analysis to investigate particularly their thermal stability. The brominated products demonstrate lower thermal effects when thermally decomposed which is caused by the retarding ability of bromine.

Polymer nanocomposites containing carbon nanoparticles have exhibited remarkable thermal, mechanical and electrical properties. This review is concerned with a narrow sector of polymer nanocomposites, namely those based on engineering polyesters, which are of great industrial interest. The various functionalization methods of modifying carbon nanotubes and graphene derivative forms to allow interacting with polymer matrices will be summarized. Moreover, the review on the processing techniques of obtaining polymer nanocomposites with the emphasis of their efect on the inal properties of the obtained material will be highlighted. The light will be also shed on the nanoiller dispersion in the polymer matrix. Finally, the opportunities and challenges in the high-performance polymer nanocomposites will be presented.Keywords: polymer nanocomposites, thermoplastic polyesters, carbon nanoparticles . IntroductionEngineering polyesters, such as poly ethylene terephthalate PET and poly butylene terephthalate P"T , constitute a group of engineering thermoplastics. However, this group is now expanded by new members of the polyester family, that is, poly trimethylene terephthalate PTT and poly ethylene-2, 6-naphthalate PEN . They combine excellent mechanical, electrical and thermal properties with very good chemical resistance and dimensional stability. Moreover, with excellent processing characteristics and high strength and rigidity, they are widely used in industrial applications. However, still at a commercial level the aforesaid properties, one can further improve through an addition of suitable modifying agents such as nanoillers.

Hybrid nanomaterials, defined as an intentional combination of at least a nanomaterial with one or more materials, at an atomic or a nanometer level of mixture, complementing each other to have new or improved functions and properties which component materials did not possess, provide new possibilities for electroanalytical methods The relevant functional properties of nanomaterials can be tuned, in an unimaginable manner, by rational combination with other materials. This fact opens an exciting door for sensor and biosensor technology, which is well supported by the advances in other areas such as surface science, organic and inorganic synthesis, polymer and biomolecular chemistry, and nanotechnology. This article provides a general sight state of the art on the use of nanosized hybrid materials as transduction, amplification, and labeling elements for the establishment of original electrochemical methods of analysis, exemplified with some of the most relevant research published in the past 5 years. The article is divided into two main categories: (i) electrochemical sensors based on hybrid nanomaterials of inorganic–organic, inorganic–inorganic, and organic–organic composition hybrid nanomaterials; (ii) electrochemical biosensors making use of metal nanostructures, carbon nanomaterials, metal and nonmetal oxide nanomaterials, and soft‐nanomaterials hybrids.
