CPM-M4 tool steel is a commonly used knife blade material due to its high strength and wear resistance. The goal of this thesis is to understand how heat treatment parameters affect blade performance and microstructure.Five heat treatments were applied to CPM-M4 steel by varying austenitizing and tempering temperatures. The microstructures...
Metal-organic frameworks (MOFs) represent an exciting, new class of porous materials. Their hybrid organic-inorganic structure opens up near infinite possibilities to tune and design their structure for specific properties and applications. A new generation of flexible MOFs, following a generation of stiff MOFs, has created additional design space and complexity....
Hydrogel polymers are a novel class of hydrophilic materials that have large application areas in both the industrial and medical fields. Carboxymethyl cellulose (CMC) has received attention as a hydrogel polymer. Methods to modify the mechanical properties of gels and films made from CMC are of interest in our lab...
Epoxy resin is a thermosetting resin that is commonly used as composite matrix. Epoxy composite materials are well utilized in industries, such as aerospace, due to their good mechanical properties. Nano-scale filler reinforced polymer composite materials have been intensively researched in recent decades. Cellulose nanocrystals (CNXLs) are a type of...
