![]() ![]() Cellulose can be isolated from plants and non-plant sources. It is a polymer that composed of amorphous and crystalline regions which varies depending on the plant species. It has a general formula (C 6H 10O 5) n, found in plants as microfibril and isolated from wide range of species from higher plants such as wood to green algae. Today, it is an important material which is widely used in industries (paper, pharm, food, etc.) and it has also served as an economic output in many countries of the world. It has become one of the material’s serving mankind for centuries and major subject in the history of polymer science in developing nation’s economic and determination of polymeric crystal structures. The linear molecules are linked laterally by hydrogen bonds to form linear bundles which give rise to the crystalline structure. It is a polymer that contains crystallites and displayed para-crystalline morphology. Studied had shown that if well harness, wood dust may attract economic values to the country rather than the usual pollution.Ĭellulose is a formation of the composite, a versatile and widely natural-based material in nature that consists of glucose molecules which has various uses to man and used by man for thousands of years as building material, or energy source. This by-product usually constitutes menace to man and his environment as the material is usually disposed of sometimes indiscriminately in different locations which most often constitute environmental pollution. One important waste from wood is the wood dust. Nigeria, with a population over 180 million as at 2018, has the largest producer of residue and solid waste in Africa. The environmental degeneration caused by solid waste from different activities had been a challenge to the waste management throughout the world. The effect of particle sizes on the thermal and mechanical properties of wood had gained popularity in recent years due to its importance in improving the insulation properties of materials. It is an organic material with a composition of cellulose, hemicellulose, and lignin which has been used for many years as a basic need in construction materials and other purposes. Wood is one of the hard fibrous structural tissue and abundant natural materials on earth. Within the limit of the research, size classification is noted to influence the characteristics of the cellulose materials. The isolated cellulose exhibits good mechanical and solid state properties with promising applications in device utilization. The surface morphology of the isolated cellulose appears fiber -like for the size classifications examined. The elemental composition consists of Carbon (C), Oxygen (O), Sodium (Na) and Chlorine (Cl) with Carbon having the highest percentage. The crystallinity and the inter-planar spacing revealed different structural properties for the two size classifications. The structure of the cellulose composed principally of crystalline cellulose (I and II) and amorphous cellulose. This study focused on the influence of size classifications on the structural and solid State characterization of cellulose obtained from wood dust. Therefore, there is need to establish the influence of size classification as it affects the properties of cellulose materials. However, it has been affirmed that increase in crystallinity index, increases the strength properties of cellulose materials. Researchers had the opinion that there exist no significant difference between the characteristics of bulk particulate materials and sizes of their constituents. Influence of size classification on the properties of cellulose materials has been a subject of neglect over the years. ![]()
