Valuable applications of NFC are reviewed for developing novel applications of Ulva prolifera. NFC was prepared using a simple grinding treatment (20000 r/min, 20 min) after the removal of polysaccharide, ester acid, protein and salt. The obtained cellulose I_α NFC had a uniform width of approximately 40 nm and a high aspect ratio. Grinding is an effective way to convert raw cellulose to nanofibrils. Furthermore, we also prepared flexible algal cellulose aerogel with a low density (23 mg/cm³) and a high specific surface area (277 cm²/g) after t-BuOH freeze-drying. It is also revealed that t-BuOH freeze-drying is an efficient way to assemble 1D NFC to meso- porous materials. All these results were confirmed by SEM, FTIR spectra, and X-ray diffraction profiles. On the basis of that, Ulva prolifera was nanofabrillated without any chemical purification by direct grinding, and algal foam was prepared with freeze-drying to fully use algae from green tide., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=WfSFlgRk4vve7EFfWJDP1Q==, pdfFileSize=3652954, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
