PCNH is defined as delignified pomelo peel (DPP)-confined carboxymethyl cellulose (CMC) nanofluidic hydrogel. Photographic and Cryo-SEM images of A DPP, B CMCH, and C PCNH. D ATR-FTIR spectra, E Zeta potential, and F I-V curves of DPP, CMCH, and PCNH. G The schematic illustration of different pore morphology between PCNH and CMCH. H The Cryo-SEM images and corresponding pore-size distribution of PCNH samples (PCNH1, PCNH2, and PCNH3) prepared by filling different amounts of CMC. The letter “D” represents the average pore diameter of the PCNH samples. I A comparison of the swelling ratio between PCNH (yellow square) and CMCH1 (green square). The inset displays the swelling behavior of these two hydrogels at different swelling time, wherein the images above and below represent the PCNH and CMCH1, respectively. CMCH1 is defined as CMC hydrogel prepared with a higher CMC solution concentration. J The morphological and microscopic changes of PCNH and CMCH1 after being exposed to moisture for about 48 h.
