Abstract
Cladophora, a fresh-water green macroalgae, has unique cellulose properties and thus may be promising for production of cellulose nanofibrils (CNFs). Cellulose was extracted from
Cladophora glomerata and subjected to microfluidization with or without enzymatic hydrolysis pretreatment to produce CNFs. Increasing microfluidization passes produced smaller algal CNFs with more uniform sizes and lower crystallinity. Combining microfluidization with an enzymatic hydrolysis pretreatment, the algal CNFs’ crystallinity decreased further, but the diameter distribution showed little change. The algal CNFs were compared to CNFs produced from bleached eucalyptus pulp (BEP), with the algal CNFs having significantly higher crystallinity, smaller diameter and better thermal stability. The XRD spectra of algal and BEP CNFs were simulated by Mercury 3.0 software.
