“…Thiazole ring as a substituent containing sulfur can contribute to the high refractive index of polymers. In our previous works, polymers containing thiazole with high refractive index, low birefringence, high thermal stability, and good solubility in common organic solvents were designed and synthesized [32][33][34][35][36].…”

New polyamide/clay nanocomposites (PACN) were produced using semicrystalline polyamide (PA) containing thiazole ring and new organoclay (OC) through solution intercalation technique. For further study, PA/Cloisite‐15A nanocomposites (PAAN) were also prepared using PA and Cloisite‐15A. X‐ray diffraction (XRD), field emission‐scanning electron microscopy (FE‐SEM), and transmission electron microscopy (TEM) results showed a good dispersion for OC in the PA matrix. A meaningful decrease in intensity of absorption from ultraviolet–visible spectra as well as from fluorescence emissions of resulted PACN were observed. As thermogravimetric analysis (TGA) in nitrogen atmospheres showed, the T5 and T10 increased by about 57% and 36%, respectively for PACN containing 5 mass% of OC, as the char yield enhanced greatly, which was about 16.3% higher than the neat PA. Also the TGA results showed that PACN had higher thermal stability than PAAN. Differential scanning calorimetry (DSC) analysis exhibited higher glass‐transition temperature values (Tg) for PACN as compared to the neat PA. POLYM.

“…7,31,32 We have reported that polyimides containing pyrimidine units exhibited high n values over 1.7. As for these polyimides, the lower transparency at the shorter visible wavelengths due to their aromatic imide-phenyl structure is, however, a critical problem for lens applications.…”

Novel poly(phenylene thioether)s containing pyrimidine rings and fluorene units in the main chain have been developed as promising candidates for thermoplastic lenses which are used for the compensating chromatic aberration. The obtained polymers showed a good thermal stability (i.e., 5% weight-loss temperature over 320 o C) and relatively high glass transition temperatures in the range of 132−201 o C. The cutoff wavelengths of the polymer thin films are shorter than 320 nm, and a transmittance higher than 90% was observed over 380 nm. The polymer containing a fluorene unit with the highest sulfur content exhibited the highest refractive index of 1.678 and the low birefringence of 0.004 at 633 nm.

“…For most of the polymeric materials in our life, their conductivities are very low because a cluster of free electrons could not flow along their backbones. For example, poly(amide-imides) (PAIs) possessing good mechanical and thermal properties have been considered to be excellent engineering materials, but their application in the conductive field has been limited due to their poor conductivity [7,8,9,10,11]. The insulator–conductor transition could be achieved by incorporating conductive fillers into the polymer matrix.…”

Highly conductive thin films with suitable mechanical performances play a significant role in modern electronic industry. Herein, a series of ternary conductive polymer composites were fabricated by incorporating carbon black (CB) into binary conductive polymer composites of poly(amide-imide) (PAI) and polyaniline (PANI) to enhance their mechanical and conductive properties simultaneously. By varying the composition of PAI/PANI/CB ternary films, the conductivity enhanced by two orders of magnitude compared with the sum of PAI/PANI and PAI/CB binary conductive polymer composites, and a high conductivity of 1160 S m−1 was achieved. The improved conductivity is mainly because much more continuous conductive networks were constructed in the ternary conductive polymer composites. With the help of the unusual morphology, the tensile strength was also enhanced by more than 80% from 21 to 38 MPa. The origin for the improved morphology was discussed for further improvement.
