Graphene oxide modified with PMMA via ATRP as a reinforcement filler
Gonçalves, Gil; Marques, Paula A. A. P.; Barros-Timmons, Ana; Bdikin, Igor; Singh, Manoj K.; Emami, Nazanin; Grácio, JoséGraphene is a two-dimensional new allotrope of carbon, which is stimulating great curiosity due to its superior mechanical, electrical, thermal and optical properties. Particularly attractive is the availability of bulk quantities of graphene (G) which can be easily processed by chemical exfoliation, yielding graphene oxide (GO). The resultant oxygenated graphene sheets covered with hydroxyl, epoxy and carboxyl...
Synthesis of polymer-based triglycine sulfate nanofibres by electrospinning
Isakov, D. V.; Martins, Albino; Gomes, E. de Matos; Bdikin, Igor; Guimarães, Ana; Dekola, Tatjana; Almeida, B. G.; Neves, N. M.; Reis, R. L.In this work we present the synthesis and characterization of polyethylene oxide (PEO) based triglycine sulfate (NH2(CH2OOH)3H2S04, TGS) nanofibres obtained by electrospinning. The fibres, with typical diameters of about 190–750 nm and above several hundred micrometres in length, present the nanocrystals of TGS embedded in a polymer matrix. The obtained nanofibres were characterized by FT-IR spectroscopy and th...
