Abstract: To overcome the limitation of SPEEK/PBI membrane, BN was introduced to the membrane in different percentages. Firstly, boron nitride was functionalized by introducing hydroxyl group using KMNO 4 , H 2 O 2 , as oxidation agents. At the same time SPEEK was prepared by sulfonating PEEK at 80 °C using sulfonic acid. Further, a SPEEK/PBI/BN blend was prepared by dissolving SPEEK/BN in DMCs and then mixed with PBI heated solution. The percentage of the BN were 10%, 15 and 20%. The prepared membranes were characterized, however, SPEEK/PBI/BN-10% showed the optimum physicochemical properties; in which the degree of sulfonating, ion exchange capacity, water uptake, tensile stress, ionic conductivity, and thermal stability were 80.53%, 2.18 meq.g−1, 6.13%,8.61 MPa, 245 mS/cm, and 316.6 °C. The results show that the addition of BN influenced the characteristics of the membrane remarkably in a positive way as the protonic conductivity increased remarkably from 170 mS/cm to 245 mS/cm. Moreover, there was a huge enhancement in the thermal stability and the ionic conductivity. • Among all the available nonperflurinated materials for electrolyte membranes, SPEEK and PBI seem to be the best option. • SPEEK membrane was modified with PBI and BN to enhance its thermomechanical and its protonic conductivity. • SPEEK/PBI/BN-10 showed the greatest properties, in which the ion exchange capacity was found 2.18meq.g−1. • On the other hand, Tensile stress, Water uptake, and Maximum temperature were 8.61 MPa, 316.6 °C, and 6.13% respectively. • The protonic conductivity enhanced remarkably from 170 mS/cm to 245 mS/cm.
