Double crosslinked chitosan–zeolite (CZ‐2) and noncrosslinked chitosan–zeolite (CZ‐0) composites were prepared and characterized by using Fourier transform infrared (FTIR) spectrometer, surface area analyzer, scanning electron microscope coupled with energy dispersive X‐ray (SEM‐EDX) spectrometer, thermogravimetric analyzer (TGA), X‐ray diffraction analyzer (XRD) and carbon, hydrogen, nitrogen (CHN) analyzer. After crosslinking, CZ‐2 showed a reduction in surface area and CHN content in comparison to chitosan, zeolite, and CZ‐0. Crosslinking resulted in improved stability of CZ‐2 in distilled water, acetic acid and NaOH as CZ‐2 recorded the lowest percentage of swelling. XRD diffractograms confirmed the formation of composites as there was a marked difference in the peak intensity at 2θ = 19.8°. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

“…As a natural microporous material, zeolite has a framework of channels with a diameter of < 1 nm. Owing to the many voids in the structure, zeolite can absorb many kinds of polymers to prepare the functional composite material [13,14] . Zeolite has been made of many membranes combined with various polymers that have been used as absorbing materials in environmental engineering [15 -17] .…”

The purpose of this paper was to investigate the surface modification of zeolite with polyethylene glycol (PEG) and the modified zeolite as a reinforcing filler partly replacing carbon black (CB) into rubber to prepare the rubber composites. The surface characteristics of zeolite modified by PEG and the unmodified zeolite were characterized by infrared (IR) spectroscopy and scanning electron microscopy (SEM). Moreover, the evaluations of the zeolite/rubber composite were carried out on characteristics such as tensile property, abrasion loss, and hysteresis heat generation with different amounts of zeolite and PEG. The results showed that the tensile strength and elongation at break of the composites were improved, and the abrasion and lag heat generation were reduced when 5 -8 phr zeolite modified by 3 wt% PEG was filled into rubber. These results indicated that the modified zeolite has a good compatibility and dispersion in rubber.

“…7(c)) that has been incorporated as co-polymer for Cs blend. Since the chemical structure of the Cs backbone is very similar to that of cellulose, it is expected that Cs could be miscible with cellulose and the blending might improve the chemical, physical, mechanical and biological properties of developed films [367][368][369]. However, the blend tends to display a reduction in the tensile strength and elongation at break as well as in Young's modulus.…”
