Effects Of Ball Milling On The Structure Of Cotton

Jan 17, 2019nbsp018332Cellulose is often described as a mixture of crystalline and amorphous material. A large part of the general understanding of the chemical, biochemical and physical properties of cellulosic materials is thought to depend on the consequences of the ratio of these components. For example, amorphous materials are said to be more reactive and have less tensile strength but comprehensive.

More recently, Song et al. described a new method to extract CNCs from raw cellulose by ball mill assisted acid hydrolysis. 43 The starting material was first ground in water using a ball mill at 1300 rpm, then treated with oxalic acid. Due to the relatively weak acidity of oxalic acid, ball milling was in this case employed as a pre-treatment.
