Abstract
Humankind evolved from a single cell to the dominant species and has been revolutionizing the world with advances in science and technology. Continuity of human civilization has posed many detrimental impacts on the ecological balance of this world due to exponential population growth, scarcities, gaps in supply and demand, pollution, geopolitical shifts, pandemic-driven socioeconomic constraints, and concurrent events. Sustainable practices are a timely projection for mitigating environmental pollution induced by excessive consumption of petrochemical products, mismanaged plastics, and ecotoxicity of industrial-agricultural wastes. Hence, there is a persisting inevitability for innovative techno-commercially viable research and developments to generate a positive environmental footprint from renewable biobased, biodegradable, or green alternatives. Nanocellulose is a one-dimensional nanomaterial and a polysaccharide engineered from abundantly found lignocellulosic sources. Considering its unique physicochemical, structural, and morphological characteristics, nanocellulose can be used as; a). polymeric subunits with favorable surface chemistries, b). reinforcing fibrous fillers for various composites/blends, c). a hydrogel with tunable mesoporous morphology, and d). an efficient carrier for reactive textile dyes.
Based on lignocellulosic chemistry, adhering to the characteristics of nanocellulose mentioned as a-d, this dissertation provides scientific inferences, discussions, and reliable insights for the following industry applications,
Chapter 3, for bioplastics and packaging: Preparation and characterization of the nanocomposites from polybutylene succinate and 1,3-dioctyl urea modified nanocellulose for biodegradable primary packaging solutions.
Chapter 4, for aerogel: Functional textile coatings from biobased lignocellulosic aerogels for thermal regulation and super absorbency.
Chapter 5, for textile dyeing: Nanocellulose-based sustainable dyeing of cotton textiles with minimized water pollution.
INDEX WORDS: Nanocellulose, biodegradable polymer composites, aerogels, textile dyes, sustainable technologies and green chemistry.
