    Effects Of Ball Milling On The Structure Of Cotton Cellulose

    Jan 17 2019 cellulose 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
