Effectively, BSTx samples are synthesized via double-sintering route. BST0.20 and BST0.30 are subjected to the particle size analysis, crystal structure analysis and dielectric and ferroelectric properties.

Two types of nanofiller were employed for the membrane reinforcement including nano-zeolite (NZ) and bifiller of nano-zeolite-carbon nanotube (NZ-CNT). The PC/PSAA/NZ-CNT membrane with 10 wt.% filler revealed the formation of gyroid type microstructure. The tensile strength of PC/PSAA/NZ 1–10 was 42.1–55.5 MPa, whereas PC/PSAA/NZ-CNT 1–10 showed higher value of 56.9–68.7 MPa. Moreover, the tensile strength of PC/PSAA/NZ-CNT 10 was 53% higher than the PC/PSAA matrix (32.2 MPa). Similarly, the Young's modulus of PC/PSAA/NZ-CNT 1–10 was increased from 133.2 to 144.2 MPa, and was found higher than the PC/PSAA/NZ 1–10 (101.1–122.1 MPa). The NZ-CNT filler was found more effective than NZ in enhancing permselectivity. The αCO2/N2 for PC/PSAA/NZ-CNT 10 was increased up to 38.2, which was higher than the PC/PSAA/NZ 10 (36.3) and neat blend (27.2).
