Contact Dewatering Of Cellulose Nanofibers For Biopolymer Composite Applications, Alexander Collins
Contact Dewatering Of Cellulose Nanofibers For Biopolymer Composite Applications, Alexander Collins
Electronic Theses and Dissertations
Cellulose Nanofibrils (CNFs) are promising materials for reinforcement of polymer matrices attributable to their impressive physical and mechanical properties, as well as their biodegradability. However, the utilization of these materials in composites is made challenging by the water content of CNF slurries, the tendency of CNFs to agglomerate as they dry, and incompatibility between hydrophilic CNFs and hydrophobic polymer matrices. The most commercially viable drying methods to produce small-scale dry CNFs, such as spray drying, are very energy intensive, can only dry the materials down to micron-scale agglomerates, and do not preserve fibrillar aspect ratios. “Contact dewatering,” or the removal …
Synthesis And Behavior Characterization Of Multi-Scale Hierarchical Structured Composites, Jacob M. Mayfield
Synthesis And Behavior Characterization Of Multi-Scale Hierarchical Structured Composites, Jacob M. Mayfield
Electronic Theses and Dissertations
The purpose of the synthesis of a multi-scale hierarchical composite material was to create a material with a high specific strength, a low mass, and high strength material. To achieve this the material categorization of the Formlabs Tough V2 resin was conducted. The resin was used in the construction of a bio-mimicry diamond lattice structure. The structure was subjected to compression testing to characterize the material properties. The Tough V2 resin structure combined with cellulose created a multi-scaled material on Macro and Micro levels to show the bio-inspired design to increase the material properties in a favorable manor. The Tough …
