Abstract

ABSTRACT 

This research was conducted to optimize the casting thickness in the preparation of Polyetherimide (PEI) membrane. PEI was performed using an immersion-precipitation-induced phase inversion method with a thickness range from 0.5 to 0.8 mm. The results of morphological analysis and cross-sections performed by using Scanning Electron Microscope (SEM) showed decreased pore size along with decreased casting thickness. The results of purified air permeability analysis using "dead end" membrane reactor showed membrane flux at 55,290.16 - 67,244,79 L / m2.h and modulus of prepared PEI rugs were in the range of 1,443,25 - 1,687,59 N / m2. Thus, PEI membrane casting thickness has resulted in increased mechanical strength and pure air permeability.

ABSTRAK

 

Penelitian ini dilakukan untuk mengoptimasi ketebalan cetak dalam pembuatan membran Polyetherimide (PEI). Optimasi ketebalan cetak membran PEI dilakukan dengan menggunakan metode inversi fasa terinduksi imersi-presipitasi dengan rentang ketebalan 0,5 0,8 mm. Hasil analisa morfologi permukaan dan penampang melintang dilakukan menggunakan Scanning Electron Microscopy (SEM) menunjukkan penurunan ukuran pori seiring dengan penurunan ketebalan cetak. Hasil analisis permeabilitas air murni menggunakan reaktor membran œDead end menunjukkan nilai fluks membran pada 55.290,16  67.244,79 L/m2.jam dan nilai modulus Young membran PEI yang dipreparasi berada pada rentang 1.443,25 1.687,59 N/m2. Dengan demikian, penurunan ketebalan cetak membran PEI telah menghasilkan peningkatan kekuatan mekanik dan permeabilitas air murni.
