Cellulose derivatives: Fundamentals and Applications

In my talk, I will first cover basic wood and cellulose chemistry. The various tissues of wood and bark are composed of complex organic matter. Usually divided into cell wall substances and non cell wall substances. Cell wall material is the basic substance that makes up wood and bark, such as cellulose, hemicellulose, and lignin, all of which are high molecular weight compounds. There are many types and low contents of non cell wall substances, which vary greatly depending on the tree species and location of their presence. They are basically low molecular weight compounds that can dissolve in water or neutral organic solvents, collectively known as extracts. The distribution of various chemical components in various tissues of wood and bark is uneven. There is an organic connection between them. Therefore, the chemical properties of wood depend not only on the relative content of various chemical components in its tissue, but also on the distribution and interrelationships of each component.
Next, I will discuss my recent research results including structure - property - performance relationships of cellulosic block copolymers and fractionation of lignocellulosic biomass via etherification.
