“…The interlayer water in QATP mostly acted as bound water, which can facilitate the transportation of protons. (c) Moreover, the proton transport channel also plays an important role in proton conductivity; the one‐dimensional (1D) crystal structure and fiber morphology of QATP are easy to construct conductive channels of protons, especially in the case of good dispersion of QATP. Thus, the proton conductivity shows an increasing trend when the QATP content increases from 1 to 2 wt%.…”

“…Feng et al modify ATP by hexadecylpyridinium chloride; the prepared PPy(polypyrrole)/ATP conductive composites exhibit improved performance of conductivity . The tertiary‐amine‐modified ATP is reported by Wang et al, the obtained SPEK (sulfonated poly[aryl ether ketone])/ATP composite membranes show higher proton conductivity than pristine SPEK . But as far as we know, there are seldom reports on this aspect.…”

The chitosan (CS) matrix‐based composite proton exchange membranes (CS/QATP) were prepared by the incorporation of organic‐modified attapulgite (QATP) into CS, through an organic‐inorganic composite synthesis method. The QATP was obtained by the modification with silane coupling agent (octadecyldimethyl [3‐trimethoxysilylpropyl] ammonium chloride). The morphology, crystallinity, thermal and mechanical property, dimensional stability, and proton conductivity of CS/QATP composite membranes were investigated. The compatibility and dispersibility of QATP in CS matrix were significantly improved with enhanced interfacial interaction. The dimensional and thermal stability of the CS/QATP composite membranes were improved compared with pure CS film, owing to good dispersion and lower water uptake. Especially, the composite membrane with 2 wt% QATP (CS/QATP‐2) exhibits the highest mechanical strength and proton conductivity, which is much higher than pure CS film. These results indicated that CS/QATP composite membranes have a great potential for proton exchange membranes applications.

A composite proton exchange membrane chitosan (CS)/attapulgite (ATP) was prepared with the organic–inorganic compounding of ATP and CS. The composite membranes were characterized by scanning electron microscope (SEM), X‐ray diffraction (XRD), and fourier transform infrared spectroscopy (FTIR). The mechanical properties, thermal stability, water uptake, and proton conductivity of the composite membranes were fully investigated. The composite membranes exhibited an enhanced mechanical property, dimensional and thermal stability compared to CS membrane, owing to the interface interaction between ATP and CS. The maximum tensile strength of 53.1 MPa and decomposition temperature of 223.4°C was obtained, respectively. More importantly, the proton conductivity of the composite membrane is also enhanced, the composite membrane with 4 wt% ATP content (CS/ATP‐4) exhibited the highest proton conductivity of 26.2 mS cm−1 at 80°C with 100% relative humidity, which is 25.1% higher than pure CS membrane. These results may explore a simple and green strategy to prepare CS‐based PEMs, which have a great potential in the application of proton exchange membrane fuel cells.
