| الوصف: | We present a novel nanostructure in the form of cellulose nanoplatelets (CNPs) with an inner array of entangled nanofibrils. The planar structure was isolated from the parenchyma cells of Agave salmiana first using basic pretreatment, then by dissolving lignin and hemicellulose using acid hydrolysis, and finally by modifying the cellulose with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO). The crystallinity index was calculated following the purification process, and it was found that nanocellulose was 30% more crystalline than the raw material. Using transmission electron microscopy, it was found that the nanoplatelets comprise ~2–3 nm long cellulose entangled nanofibrils. In addition, via atomic force microscopy, the morphology of the nanoplatelets was confirmed; they were 90 nm thick for the acid hydrolyzed sample and 70 nm thick for the TEMPO-modified sample; their lateral size varied from a few to hundreds of micrometers, presenting large aspect ratios. Finally, CNPs were isolated and processed into thin paper with a thickness of 100 µm and transmittance of 86%, demonstrating great potential as a transparent film. |
