“…Fourier transform infrared spectra of the hydrogels are consistent with the results of thickness and gel fraction determination that electron beam irradiation may reduce GO, causing less functional groups to appear on the GO surface . It also suggests uniform dispersion and insufficient amounts of GO (wt % < 0.1) in the BNC/PAA matrix .…”

Graphene oxide (GO) is a potential material for wound dressing due to its excellent biocompatibility and mechanical properties. This study evaluated the effects of GO concentration on the synthesis of bacterial nanocellulose (BNC)-grafted poly(acrylic acid) (AA)-graphene oxide (BNC/P (AA)/GO) composite hydrogel and its potential as wound dressing. Hydrogels were successfully synthesized via electron-beam irradiation. The hydrogels were characterized by their mechanical properties, bioadhesiveness, water vapor transmission rates (WVTRs), water retention abilities, water absorptivity, and biocompatibility. Fourier transform infrared analysis showed the successful incorporation of GO into hydrogel. Thickness, gel fraction determination and morphological study revealed that increased GO concentration in hydrogels leads to reduced crosslink density and larger pore size, resulting in increased WVTR. Thus, highest swelling ratio was found in hydrogel with higher amount of GO (0.09 wt %). The mechanical properties of the composite hydrogel were maintained, while its hardness and bioadhesion were reduced with higher GO concentration in the hydrogel, affirming the durable and easy removable properties of a wound dressing. Human dermal fibroblast cell attachment and proliferation studies showed that biocompatibility of hydrogel was improved with the inclusion of GO in the hydrogel. Therefore, BNC/P(AA)/GO composite hydrogel has a potential application as perdurable wound dressing.

“…The GO and SGO specimens exhibited an identical absorption peak at 230 nm, indicating that the optical properties of the GO were not significantly affected by the aryl diazonium reaction-based sulfonation. On the other hand, the absorption peak of all SRGO samples prepared at the given absorbed doses was present at a longer wavelength of 265 nm in comparison to that of the SGO [16]. In addition, as shown in the inset ( Fig.…”

We report the preparation of sulfonated reduced graphene oxide (SRGO) by the sulfonation of graphene oxide followed by radiation-induced chemical reduction. Graphene oxide prepared by the well-known modified Hummer's method was sulfonated with the aryl diazonium salt of sulfanilic acid. Sulfonated graphene oxide (SGO) dispersed in ethanol was subsequently reduced by γ-ray irradiation at various absorbed doses to produce SRGO. The results of optical, chemical, and thermal analyses revealed that SRGO was successfully prepared by γ-ray irradiation-induced chemical reduction of the SGO suspension. Moreover, the electrical conductivity of SRGO was increased up to 2.94 S/cm with an increase of the absorbed dose.

“…1,15 The poly(methyl methacrylate) (PMMA) is a hightransparency amorphous hydroscopic biocompatible thermoplastic polymer with excellent optical clarity and stability upon positron radiation, which can be converted by irradiation from an insulating to a conducting form. [16][17][18][19] PMMA is commonly used in industrial applications, especially in shatterproof windows, illuminated signs, optical and electronic components, and also in microstructures prepared by ion beams. 20,21 The use of PMMA for capacitive humidity sensor preparation has been reported previously in earlier works.…”

Carbon beam writing was employed as a method for maskless production of microscale capacitors in both insulating graphene oxide (GO) and poly(methyl methacrylate) (PMMA) matrix. The GO and PMMA foils were irradiated using a 5-MeV C 3+ beam with micrometer scale resolution. As follows, the shape of the created microstructures and compositional changes was studied using the scanning electron microscopy/energy-dispersive X-ray spectroscopy method (SEM/EDS). The structural and compositional progression was characterized by Raman spectroscopy, Rutherford backscattering spectroscopy (RBS), and elastic recoil detection analysis (ERDA) spectroscopy. The improvement of the prepared structures' electrical properties was also studied, and it can be concluded that carbon irradiation leads to the removal of oxygen and hydrogen and to growth of the carbon domains, which is connected with the conductivity increase of the irradiated parts and capacitance of the final products in the order of pF.
