Preparation of HPMC-NP and the loading iodine. a Interfacial deposition of PANi on the cellulose wiper via an oxidative polymerization in the presence of phytic acid and the subsequent carbonization in N2 atmosphere. Then, iodine is escasulated into the as-prepared HPMC-NP from the iodine-saturated solution. b The digital photograph, c, d SEM images (Scale Bar, 1 mm and 500 nm, respectively), and e, f TEM images of the free-standing HPCM-NP (Scale Bar, 100 nm and 20 nm, respectively). g SEM image (Scale Bar, 15 μm) and the corresponding elemental mapping of the iodine loaded HPCM-NP
