In this investigation, carboxymethyl cellulose (CMC)‐reinforced poly(vinyl alcohol) (PVA) were prepared with trimethylol melamine as a chemical crosslinker. The structure and property of hydrogels were measured by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), texture analysis, and rheometry. The FTIR spectra demonstrated that the etherification reaction successfully occurred in the PVA–CMC hydrogels, and the SEM figures exhibited the homogeneous porous structure of the CMC–PVA hydrogels. The compression strength of the PVA–CMC hydrogels was 15 times higher than that of the PVA hydrogels. Moreover, the PVA–CMC hydrogels exhibited a higher storage modulus than that of the PVA hydrogels; this illustrated better elasticity for the PVA–CMC hydrogels. As a result, CMC‐modified PVA hydrogels with high mechanical behavior will broaden the potential applications of hydrogels, such as in wound dressings, facial masks, and skin‐protection layers. © 2016 Wiley Periodicals, Inc.
