Microcrystalline cellulose (MCC) aerogels were synthesized, blendingwith high amylose\ncorn starch of different contents based on a NaOH-urea solution, and following by vacuum\nfreeze-drying technology. The microstructure of the aerogel was observed by scanning electron\nmicroscopy (SEM) as an interconnected, porous three-dimensional structure, while X-ray diffractogram\n(XRD) measurements showed that the crystalline form was converted from cellulose I to cellulose II\nduring dissolution and regeneration. Thermogravimetric analysis (TGA) showed that the content of\nstarch had little effect on the thermal stability of the aerogel, whereas the content of starch had great\ninfluences on absorption and viscoelastic properties. When the ratio of starch was 10% and 15%, the\nprepared aerogels presented a low density and abundant pores, which endowed the aerogels, not\nonly with the highest absorption ratio of pump oil and linseed oil (10.63 and 11.44 g/g, respectively),\nbut also with better dynamic viscoelastic properties.
