Method for detecting structural characteristics of redispersed and concentrated micro/nano cellulose

The invention discloses a method for detecting structural characteristics of redispersed and concentrated micro/nano cellulose, and belongs to the field of micro/nano cellulose. The method comprises the following steps: grinding cellulose slurry, concentrating the obtained suspension, adding polyethylene glycol and a glucan probe molecule solution into an obtained concentrated micro/nano cellulose system, and obtaining a redispersed micro/nano cellulose/probe molecule mixed solution under the mechanical action of a high-speed emulsifying machine. And centrifuging the mixed solution, taking out supernate, and detecting and calculating the supernate through a high performance liquid chromatograph to obtain the total pore content and pore size distribution of the redispersed and concentrated micro/nano cellulose so as to characterize the structural characteristics of the redispersed micro/nano cellulose. According to the method, the structural characteristics of the redispersed and concentrated micro/nano cellul
