“…Sementara itu, modifikasi kitosan dengan anhidrida suksinat akan meningkatkan kerapatan muatan, dapat menghasilkan senyawa kitosan suksinat yang tidak mudah larut dengan derajat subtitusi yang tinggi, dengan gugus -COOH rantai ujung yang mudah terionisasi sehingga berpotensi menjadi penghantar ion (Ramadhan et al, 2012). Dengan potensinya sebagai penghantar ion, material tersebut perlu dimodifikasi dan dimanfaatkan sebagai material alternatif seperti penghantar ion litium pada rangkaian membran elektroda dalam baterai polimer litium dan memperbaiki sifat mekanik membran.…”

ABSTRAKSifat mekanik merupakan salah satu karakter yang penting dalam pengembangan material polimer fungsional seperti membran elektrolit yang berpotensi untuk penghantar litium. Dalam penelitian yang telah dilakukan, membran elektrolit disintesis dengan bahan dasar kitosan suksinat dan kitosan, serta litium. Membran dipreparasi melalui metode inversi fasa dengan variasi komposisi fraksi massa kitosan suksinat dan kitosan. Selanjutnya dilakukan uji sifat mekanik. Hasil penelitian menunjukkan bahwa peningkatan fraksi massa kitosan suksinat sampai dengan 60 % (b/b) cenderung meningkatkan kekuatan tarik dan perpanjangan, serta menurunkan Modulus Young. Pada fraksi massa kitosan suksinat 70 % sampai dengan 80 % (b/b), kekuatan tarik dan perpanjangan cenderung menurun, serta Modulus Young meningkat. Nilai maksimum kekuatan tarik, perpanjangan, dan Modulus Young masing-masing adalah 0,18 MPa, 112 %, dan 14,31 MPa. Berdasarkan hasil analisis sifat mekaniknya, membran paduan kitosan suksinat-kitosan terinsersi litium memiliki stabilitas mekanik yang cukup baik. ABSTRACTMechanical properties is one of the important character in the development of functional materials such as polymer electrolyte membrane that potential for lithium conductor. In this research, electrolyte membrane based on chitosan succinate and chitosan, as well as lithium was synthesized. The membranes were prepared by phase inversion method with a variation of the composition of the mass fraction of chitosan succinate and chitosan, then testing in the mechanical properties. Results of study showed that the increase in mass fraction of chitosan succinate up to 60 % (w/ w) tends to increase the tensile strength and elongation, and decrease the Young's modulus. At the mass fraction of chitosan succinate 70 % to 80 % (w/w), tensile strength and elongation tend to decrease, and the Young's modulus increases. The maximum value of tensile strength, elongation, and Young's modulus of each is 0.18 MPa, 112 %, and 14.31 MPa. Based on the results of mechanical properties analysis, polyblend membrane of chitosan succinate-chitosan obtained by insertion lithium has a good mechanical stability.

Sulfonated poly(ether ether ketone) (SPEEK) membranes were modified by impregnation with the ionic liquid (IL) 1‐butyl‐3‐methylimidazolium tetrafluoroborate (BMI.BF4) by immersion into an IL aqueous solution for different periods of time. The modified membranes were investigated by thermogravimetric analyses (TGA), differential scanning calorimetry (DSC), ion exchange capacity (IEC), and conductivity. The SPEEK membrane immersed into the IL aqueous solution for 2 min showed greater dimensional and thermal stability than the pristine SPEEK membrane, and achieved higher decomposition temperatures. It also presented a higher conductivity value (1.0 mS cm−1), indicating that BMI.BF4 is a promoter of proton conductivity. The membrane electrode assembly (MEA) produced reached maximum values of power density of 0.13 W cm−2 and current density of 0.54 A cm−2 during fuel cell operation. The results indicate that the SPEEK membrane modified by immersion for 2 min is promising for use in a proton exchange membrane fuel cell. Its performance yielded values very close to those obtained with Nafion, which reaches maximum values of power density of 0.19 W cm−2 and current density of 0.77 A cm−2. POLYM. ENG.
