This effectively adds to the quality of the robot. This robot is capable of taking the design of three different creatures, namely: a bird, a dinosaur and a rat. This robot

FTIR studies confirm the complexation between PVC/PMMA blends. The CCl stretching mode at 834 cm-1 for pure PVC is shifted to 847 cm-1 in PVC-PMMA-LiCF3SO3 system. This suggests that there is interaction between Cl in PVC with Li+ ion from LiCF3SO3. The band due to OCH3 at 1150 cm-1 for PVC-PMMA blend is shifted to 1168 cm-1 in PVC-PMMA-LiCF3SO3 system. This shift is expected to be due to the interaction between Li+ ion and the oxygen atom in PMMA. The symmetric vibration band and the asymmetric vibration band of LiCF3SO3 at 1033 and 1256 cm-1 shifted to 1075 and 1286 cm-1 in the DBP-EC plasticized PVC-PMMA-LiCF3SO3 complexes. The interaction between Li+ ions and SiO2 will lead to an increase in the number of free plasticizers (which does not interact with Li+ ions). When the silica content increases from 2% to 5%, the intensity of the peak at 896 cm-1 (due to the ring breathing vibration of free EC) increases in PVC-PMMA-LiCF3SO3-DBP-EC system.

Measurements of conductivity and dielectric were carried out on these films as a function of frequency at various temperatures. It was observed that PEO-LiCF3SO3 polymer electrolytes have higher conductivity. The interaction between PEO and Li salts were studied by Fourier transform infrared (FTIR).

Interaction between PVC and LiCF3SO3 was confirmed by C–H rocking mode at 1,255 cm−1 for PVC shift to 1,252 cm−1 in

Due to increasing concern over the environmental considerations, society demands adequate and secure electricity not only at the cheapest possible price,

This communication covers the influence of different proportions of [Amim] Cl concentration in plasticising the CS: LiTFSI matrix in term of the degree of co-ordination, ionic conductivity and relative viscosity. The possible dipole-dipole interaction between the chemical constituents was confirmed based on the Fourier transform infrared analysis. The highest ionic conductivity of 4.18 x 10(-4) S m(-1) was achieved at room temperature for the composition of CS : LiTFSI : [Amim] Cl (14 wt-% : 6 wt-% : 80 wt-%). The incorporation of environmental-friendly [Amim] Cl in the polymer electrolyte is significantly important in improving the ionic conductivity by increasing the amorphous morphology that consequently improves the ion transport mechanism. The highest conducting sample possesses the lowest relative viscosity with the value of 3.98 attributed to the greater structural disorderliness.
