“…We use these data to determine the appropriate light exposure to ensure that seamless composites are formed, since irregularities at the layer interfaces will interfere with light transmission through the composites. Additional reference to kinetics of photopolymerization of nanofilled DEGDA can be found in a recent publication [ 1 ]. In addition we have applied for a US patent on various aspects of this work [ 2 ].…”

This paper considers inkjet printing of optical quality 3D nano-composites from diethylene-glycol diacrylate monomer (DEGDA) containing ZrO 2 nanoparticles at varying concentrations. One application for the composites is for gradient refractive index (GRIN) lenses. The process involves printing of a nanoparticle loaded monomer "ink" onto a substrate and then photopolymerizing the monomer layer by layer using UV light. The results of the study confirm that the presence of nanoparticles favorably affects the reaction kinetics. The reaction rate and chemical conversion are enhanced considerably by the nanoparticles. A seamless interface between the layers, which are 20 m thick, may be achieved if the conversion level of the layer onto which ink is deposited is limited at 60 to 80 %. Dynamic mechanical analysis (DMA) data indicate that both the glass transition and sub Tg viscoelastic properties are influenced by the nanoparticles. When nanoparticles are introduced the Tg relaxation shifts to lower temperatures and a sub Tg relaxation appears whose intensity increases with particle concentration. These results are consistent with a molecular confinement model involving a lower crosslink density rubbery layer at the polymer-particle interfaces.

“…[79,82] For example, compatibilizing surface ligands such as silanes on ZnO nanoparticles is thought to considerably increase conversion in the crosslink reaction in the UV photopolymerization process during inkjet printing, thereby leading to additively manufactured nanocomposites with improved thermal and mechanical properties. [83] Photopolymerization kinetics were also improved significantly by using water-dispersible photoinitiator nanoparticles based on 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO).…”

With an exponential rise in the popularity and availability of additive manufacturing (AM), a large focus has been directed toward research in this topic's movement, while trying to distinguish themselves from similar works by simply adding nanomaterials to their process. Though nanomaterials can add impressive properties to nanocomposites (NCs), there are expansive amounts of opportunities that are left unexplored by simply combining AM with NCs without discovering synergistic effects and novel emerging material properties that are not possible by each of these alone. Cooperative, evolving properties of NCs in AM can be investigated at the processing, morphological, and architectural levels. Each of these categories are studied as a function of the amplifying relationship between nanomaterials and AM, with each showing the systematically selected material and method to advance the material performance, explore emergent properties, as well as improve the AM process itself. Innovative, advanced materials are key to faster development cycles in disruptive technologies for bioengineering, defense, and transportation sectors. This is only possible by focusing on synergism and amplification within additive manufacturing of nanocomposites.

Additive Manufacturing In article number 2103334, Hilmar Koerner and co‐workers discuss how, with the growth in additive manufacturing, such as 3D printing, nanocomposites have experienced a resurgence due to novel emergent material properties, which are enabled by digitally dialing in morphology over several length scales. Topology optimization of 3D printed nanocomposites takes this to another level with unprecedented control over morphology and material response in structural and electro‐optical applications.
