Abstract

The invention belongs to the field of high polymer materials and particularly discloses cornstalk nanocellulose whiskers and a preparation method and application thereof. The molecular chain structural formula of the cornstalk nanocellulose whiskers is shown as in the described formula (1), wherein n is a natural number less than 200, and the molecular weight of cornstalk nanocellulose is 10000-30000. The preparation method of the cornstalk nanocellulose whiskers is simple, and high-temperature high-pressure hydrolysis pretreatment is adopted for full fibering; compared with acid or alkaline pretreatment in other nanocellulose preparation methods, the pretreatment method has the advantages that chemicals in the pretreatment process are saved, difficulty in treatment of waste fluid in the pretreatment process is lowered, and further acid concentration of subsequent acid hydrolysis cellulose can be lowered.

Description

technical field

[0001] The invention belongs to the field of polymer materials, and in particular relates to a corn stalk nano-cellulose whisker and a preparation method and application thereof. Background technique

[0002] With the improvement of people's living standards, the consumption of resources and energy is also increasing, resulting in the shortage of resources and the aggravation of the energy crisis. In the process of people looking for solutions to problems, the development and utilization of biomass energy has become more and more aroused. people's attention. In nature, cellulose is a high-molecular substance synthesized by plants through photosynthesis. The global annual output is as high as several hundred million tons. It is a natural organic high-molecular material with abundant sources and low price. There are abundant fibers in corn stalks white. However, natural cellulose has certain defects in physical form and chemical properties, such as low streng...
