“…The objective of this research work is to develop high-performance of modified membranes and investigate the effect of zeolite addition on the morphological, thermal and mechanical properties of the developed membranes by using the instrument of Fourier transform-infrared, scanning electron microscope, thermogravimetric analysis, universal testing machine and X-ray diffraction. Meanwhile, the membranes pervaporation performance already discussed in our previous paper [20].…”

“…The addition of LNZ particles into the CA matrix solution resulted in a larger viscosity than of the CA solution. Thus, the viscosity of mixture would increase with the increase of mass content of LNZ, which was resulting an increase of the dehydration performance of ethanol on the pervaporation process [20].…”

“…Previous studies of modified cellulose acetate membranes with hydrophilic NaA zeolite fillers resulted in membranes that were densified that could increase membrane selectivity to hydrophilic materials [8][9][10]. Gamma irradiation of the cellulose acetate membrane by the addition of glutaraldehyde as a cross-linker can improve both physical and mechanical properties [11] evidenced by decreasing degrees of swelling and increased tensile strength.…”

Cellulose acetate blend membranes in this study synthesized from cellulose acetate (CA) of rice husk and NaA zeolites (Z) with N,N’-Methylene bis acrylamide (MBA) as cross-linker agent and gamma-rays from cobalt-60 source as a reaction initiator. Application of the membrane was carried out to increase the concentration of vetiverol in vetiver oil. The steps in this study were isolation the cellulose rice husk with alkali treatment, delignification, acetylation, preparation the cellulose acetate-NaA zeolites NaA-membrane by inverse phase technique, addition N,N’-Methylene bis acrylamide, and irradiation by gamma-rays. Swelling degree, crosslinking yield, tensile strength, membrane performance, FTIR, and SEM analysis were observed. The results obtained that the optimal irradiation dose for synthesis CA-Z-MBA membrane is 20 kGy. The CA-Z-MBA membrane has swelling degree of 4.44%, the tensile strength of 656.40 kg/cm2, and crosslinking yield of 6.61%. Performance of the CA-Z-MBA membrane reached the flux of 60.58 g/m2.h, and permeate concentration (CP) of 11.67%, the CP increase 5 times from 2.40% to 11.67%.

“…For this reason, the use of reinforcement or filler is needed to improve the tensile strength of CA [ 17 ]. Several studies have been conducted to improve the mechanical properties of CA using organo-clay, zeolite, microfiber, lignin, and nanocellulose as reinforcement [ 18 , 19 ].…”

Preparation and Characterization of Cellulose Acetate Film Reinforced with Cellulose Nanofibril

et al. 2021

In this study, cellulose acetate (CA)/cellulose nanofibril (CNF) film was prepared via solvent casting. CNF was used as reinforcement to increase tensile properties of CA film. CNF ratio was varied into 3, 5, and 10 phr (parts per hundred rubbers). Triacetin (TA) and triethyl citrate (TC) were used as two different eco-friendly plasticizers. Two different types of solvent, which are acetone and N-methyl-2-pyrrolidone (NMP), were also used. CA/CNF film was prepared by mixing CA and CNF in acetone or NMP with 10% concentration and stirred for 24 h. Then, the solution was cast in a polytetrafluoroethylene (PTFE) dish followed by solvent evaporation for 12 h at room temperature for acetone and 24 h at 80 °C in an oven dryer for NMP. The effect of solvent type, plasticizers type, and CNF amount on film properties was studied. Good dispersion in NMP was evident from the morphological study of fractured surface and visible light transmittance. The results showed that CNF has a better dispersion in NMP which leads to a significant increase in tensile strength and elastic modulus up to 38% and 65%, respectively, compared with those of neat CA. CNF addition up to 5 phr loading increased the mechanical properties of the film composites.
