“…The absorption band at 2250-2400 cm 1 , which corresponds to the triple C≡N stretching mode, increased considerably for the hydrazine-treated silver nanowire TCEs. 15,16 When the hydrazine concentration was increased, the absorption intensity of the 2250-2400 cm -1 band increased. Therefore, this absorption band is thought to be related to the bonding between the carbon of the silver nanowire capping layer to the nitrogen of the hydrazine.…”

This paper introduces a simple hydrazine treatment method to reduce the yellowing of silver nanowire transparent conductive electrodes. To investigate the effects of hydrazine treatment on the yellowing of silver nanowire electrodes, the optical and electrical properties of silver nanowire electrodes were analyzed before and after hydrazine treatment. The optimal hydrazine treatment conditions were investigated by varying the concentration and thickness of hydrazine; the effect of hydrazine treatment on the long-term stability of silver nanowires was also analyzed.

“…The surface of the CNTs could be modified to reduce hydrophobic properties as well to improve interfacial adhesion to the bulk polymer by chemical attachment. [80][81][82][83][84][85][86][87][88][89] The knowledge of physical and chemical characteristics of CNTs as well as their reactions in organic solvents present very important role in designing, producing and utilizing of their counterparts which could have improved properties. CNTs derivatives are soluble in organic solvents (e.g.…”

“…The obtained chemically functionalized nanotubes (chf-MWCNT) were washed with deionized water till the pH 7.0, and then dried under vacuum for 12 h at 60 °C. In the second method, functionalized MWCNTs were obtained from pristine MWCNTs by using γ irradiation as it was described in previous reports [8,29]. In brief, MWCNTs were sonicated in water, then were irradiated by using a gamma ray flux from 60 Co nuclide with the photon energy of 1.3 MeV at the Radiation sterilization unit (Vinča Institute of Nuclear Sciences, University of Belgrade, Serbia) with the dose rate of 10 kGy h −1 .…”

“…In general, functional groups such as -COOH or -OH can be created on CNTs during oxidation by oxygen, air, aqueous hydrogen peroxide, concentrated sulphuric acid, nitric acid or acid mixtures [6,7]. Also, this type of CNT functionalization can be achieved by using high energy irradiation techniques [8]. The extent of functionality induced by -COOH and -OH groups depends on the oxidation procedures and oxidizing agents [9].…”

This paper presents influence of the type of carbon nanotube functionalization on properties of poly(L-lactide) (PLLA) based nanocomposite materials. For this purpose surface modifications of multi-walled carbon nanotubes (MWCNTs) were performed by chemical and irradiation techniques, while thermo gravimetric analysis, UV-Visible and Fourier-transform infrared (FT-IR) spectroscopies confirmed successful covalent functionalization. Series of PLLA bionanocomposites with different contents of functionalized MWCNTs (0.7; 1.6; 2.1 wt%), were synthesized via ring-opening solution polymerisation of L-lactide. FT-IR analysis confirmed that grafting of Llactide, under controlled condition, is possible to perform starting from the surface of functionalized MWCNTs. From differential scanning calorimetry results it was concluded that even low contents of chemically and irradiation functionalized MWCNTs had a significant effect on thermal properties of the prepared nanocomposites, raising the values of melting and glass transition temperatures. Thermogravimetric analysis (TGA) has shown that the degradation onset temperature for composites with chemically functionalized MWCNTs, was much higher than that for the neat poly(L-lactide) sample and composites with irradiation functionalized MWCNTs. Morphology studies by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicated that poly(L-lactide) covered surfaces and separated functionalized MWCNTs. Good dispersion of carbon nanotubes in polymer matrix enabled conductivity of synthesized materials, as determined by conductivity tests.
