The authors proposed Aqueous counter collision (ACC) process, which is a gentle and rapid method, to prepare separate cellulose nanofibers (ACC-nanocellulose) as dispersion in water using only a pair of water jets, without the need for any chemical modifications. Although the surface of nanocellulose has been widely presumed as highly hydrophilic, the ACC process has shown the capability to impart hydrophobic faces onto the nanocellulose surfaces, resulting in amphiphilic Janus faces.<br/><br/>     The unique amphiphilic surface properties of non-modified ACC-nanocellulose, exhibited adsorption capability to surfaces on hydrophobic resins such as polypropylene (PP). Therefore, this paper attempts to clarify availability of adsorption for the amphiphilic Janus ACC-nanocellulose onto various surfaces of widely used resins. Not only PP particles but other surfaces were expected to be applicable for the adsorption of ACC-nanocellulose. However, the result exhibited that the adsorption was better for PP rather than other plastic resins, and moreover the ability was found more or less for any plastic resin except PET. In fact, the surface on PET particles indicated almost no adsorption with ACC-nanocellulose. Reversely taking this into consideration, we could find a suitable container for our resin- adsorbable nanocellulose.
