“…It is believed that the total control of the whole conducting polymer-based composite system and the optimization of their physical properties [6]. Nanosized fillers have been introduced in a wide spectrum of applications ranging from providing photo-catalyst activation and conductivity [7,8] to improving melt processability [9][10][11][12] and moisture barrier properties. The special properties of nanoparticles are due to their size and high relative surface area to volume ratio.…”

Titanium dioxide nano filler (TiO 2 ) with (10 nm) particle size, and (0.5 wt%) was used as a dopant to epoxy type (SR8100), polymer matrix nanocomposite (PMNC) was prepared by hot vibration dispersion, and tested using FTIR, and UV spectra. It has been found that transmission of (PMNC) largely enhanced, and absorption of UV radiation reaches up to (52%) at (500 nm), (50%) at (1000 nm), and never drop to zero.

“…The other strong band absorption at 510 cm −1 and 441 cm −1 indicates the presence of Al-O stretching and Si-O bending, respectively, in the clay. The FH MMT, HMFA-MMT, and DFAT-MMT spectra show the major bands of FH, HMFA, and DFAT spectra [24][25][26] in addition to the bands of the original Na-MMT. The band at around 1,472 cm −1 suggests the existence of the ammonium ion.…”

“…Organoclay was prepared with a cationic exchange process, where Na + in the montmorillonite was exchanged with alkylammonium ion from FNCs synthesized from triacylglycerides, which were reported in our previous papers [24][25][26], in an aqueous solution. 4.00 g of sodium montmorillonite (Na-MMT) was stirred vigorously in 600 ml of hot distilled water for 1 hour to form a clay suspension.…”

Clay modification was carried out by treatment of fatty nitrogen compounds (FNCs); fatty hydrazide (FH), hydroxy methyl fattyamide (HMFA), and difatty acyl thiourea (DFAT) were synthesized from vegetable oils with a sodium montmorillonite (MMT) as natural clay. This process was accomplished by stirring the clay particles in an aqueous solution of FH, HMFA, and DFAT, by which the clay layer thickness increased from 1.23 to 2.69, 2.89 and 3.21 nm, respectively. The modified clay was then used in the preparation of the polylactic acid/epoxidized palm oil (PLA/ EPO) blend nanocomposites. The interaction of the modifier in the clay layer was characterized by X-ray diffraction (XRD) and Fourier transform infrared (FTIR). Elemental analysis was used to estimate the presence of FNCs in the clay. The nanocomposites were synthesized by solution casting of the modified clay and a PLA/EPO blend at the weight ratio of 80/20, which has the highest elongation at break. The nanocomposites were then characterized using XRD, transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and tensile properties measurements. Improvement in mechanical properties of the FH-MMT, HMFA-MMT, and DFAT-MMT nanocomposites was obtained when 2% of the DFAT-MMT and 3% of both FH-MMT and HMFA-MMT loadings were used. PLA/EPO modified clay nanocomposites show higher thermal stability in comparison with those of the PLA/EPO blend. The XRD and TEM results confirmed the production of nanocomposites.

“…In addition to medicine application of fattythioic acids due to their biological activities 8,9 , the presence of long chains fatty acids from palm oil mainly 16 and 18 carbon atoms containing O, S and N atoms suggests that fatty amides should be very useful as organic reagents for extraction and separation of metal ions from aqueous solution 5 . Additionally, it is predicted that fatty thiohydroxamic acids will offer the potential application as surfactants for many applications including clay modifi cation to produce polymer nanocomposites [10][11][12][13] .…”
