“…Then the mixture was tableted by a machine under a 10 t/cm 2 pressure for 1 min to keep all pellets in the same thickness and uniformity as possible. The dried sample was mixed with KBr and the wavenumber range scanned was 4000-400 cm 21 . The X-ray photoelectron spectra (XPS) analysis was conducted on a Kratos XSAM800 XPS analyzer with a monochromtic Al Ka X-ray source (hm 5 1486.6 eV), operated at 180 W (12 kV and 15 mA) and a pressure of 2 3 10 27 Pa.…”

“…All O1s values for NaCMC/Tb nanocomposites are higher than that of NaCMC. On the one hand, this effect is caused by decreasing delocalization of valence electron density from the metal ion to the oxygen with increasing I 1 because the I 1 of Na 1 is 489.5 kJ mol 21 and Tb 31 of that is 565.8 eV, in which the I 1 of Tb 31 is higher than that of Na…”

“…For NaCMC/Tb nanocomposites, no major changes are observed in FTIR frequency when compared with that of pure NaCMC, suggesting that the reaction between Tb salts and NaCMC is a simple metal displacement reaction. However, a new narrow shoulder band appeared at 1453 cm 21 , especially for G1, G2, and G3, which indicates the difference of intermolecular structure of NaCMC/Tb complexes from that of pure NaCMC due to the trivalent Tb ion.…”

Lanthanide metal complexes as novel luminescent metal‐organic frameworks with potential application such as probes, sensors and labels, have greatly been developed. This paper presents novel nanocomposites by reacting terbium salt with the sodium carboxymethyl cellulose (NaCMC) at different pHs, Which were characterized by SEM, TEM, FTIR, XPS, WAXD, GPC, UV‐Vis, and PL. The results show that Tb3+ ions react with O of COO‐, ‐OH, and ‐COC on NaCMC. The morphologies of these nanocomposites showed spheroidal‐like with the size around 100 nm at around neutral pH, but show rod‐like and band‐like around 100 nm in width and about 500 nm in length at pH = 11 and 12. They emit bright green characteristic fluorescence of Tb3+ under ultraviolet light due to the antenna effect when NaCMC transfer the energy efficiently to the Tb ions around neutral pHs. However, at higher pH, they show weaker fluorescence intensity in spite of strong crystalline because abundant Na+ are involved in them and affected the efficiency of energy transfer between NaCMC and Tb3+. These nanocomposites could find potential biological applications base on their fluorescent and biodegradable properties. POLYM. COMPOS., 38:E498–E507, 2017. © 2016 Society of Plastics Engineers

“…Since ammonium salts have been considered as a good proton donor, ammonium carbonate (AC) has been chosen as the ionic dopant in this SPE system [12]. On top of that, AC contains high weight percentage of hydrogen since it has 2 ammonium group (NH 4 ) [13].…”

The cellulose based solid polymer electrolytes (SPEs) containing carboxymethyl cellulose doped with ammonium carbonate (AC) have been prepared via solution casting techniques. The XRD analysis shows that the SPE films are amorphous in nature. FTIR spectroscopy shows that the occurrence of interaction between AC salt and the polymer matrix at wavenumber range of 800-1800 cm -1. Impedance measurement shows that the highest ionic conductivity was achieved at 7.71×10 -6 S cm -1 (7 wt% AC) obtained at 303 K. The ionic conductivity of SPE films at different salt concentration were revealed to follow Arrhenius law and thermally assisted.
