We demonstrate the preparation of siloxane-based and epoxy-based liquid crystal elastomers (LCEs) and LCE nanocomposites. The LCEs are characterized with respect to reversible strain, liquid crystal ordering, and stiffness. As a potential application, we demonstrate their use as shape-responsive substrates in a custom device for active cell culture.

Reactive oxygen species are chemically active, oxygen-derived molecules capable of oxidizing other molecules. Because of their reactive nature, there are many deleterious effects associated with unchecked ROS production, including structural damage to DNA and other biological molecules. However, ROS can also be mediators of physiological signaling. There is accumulating evidence that ROS play significant roles in everything from activation of transcription factors to the mediation of...

Reactivity of Enols

Enols are a class of compounds where a hydroxyl group is attached to a carbon–carbon double bond, which implies that it is a vinyl alcohol. A carbonyl compound with an α hydrogen undergoes keto–enol tautomerism and remains in equilibrium with its tautomer, the enol form. Usually, the keto tautomer is present in a higher concentration than the enol tautomer due to the higher bond energy of C=O compared to C=C. Moreover, the direction of the keto–enol equilibrium is governed by factors like...
FAQs
Effective nanoscale dispersion helps distribute the reactive constituents throughout the continuous matrix, while strong interfacial interactions improve bonding between the phases. Together, these features determine how efficiently the material develops enhanced mechanical, thermal, electrical, or barrier behavior. Poor control of either factor can prevent the intended nanoscale architecture from producing consistent performance.
These reactions modify the chemistry of the matrix, nanofillers, or their interface during processing or service. Curing and crosslinking can establish a strengthened material structure, while surface functionalization can improve bonding between nanofillers and the surrounding matrix. The resulting chemical control helps engineers tailor performance rather than relying only on the physical presence of nanoscale constituents.
Their nanoscale constituents provide additional control over interfacial interactions, chemical reactions, and material architecture. Instead of depending only on the properties of a matrix and larger reinforcement, engineers can adjust curing, crosslinking, or surface chemistry to influence several behaviors simultaneously. This approach can produce combinations of strength, thermal stability, electrical response, barrier performance, and low weight beyond conventional composite designs.
Performance depends on how the nanoscale constituents are dispersed, how they interact with the matrix, and whether the intended reactions occur during processing or service. The selected matrix, nanoscale architecture, and chemical modification therefore work together to determine the outcome. Changing these factors can shift the balance among mechanical strength, thermal stability, electrical behavior, barrier performance, and responsiveness.
Engineers first select a continuous matrix and nanoscale constituents according to the desired function, then control their dispersion and interfacial chemistry. Processing or service conditions are used to enable reactions such as curing, crosslinking, or surface functionalization. The resulting material is evaluated through its targeted mechanical, thermal, electrical, barrier, or responsive behavior to guide further design.
Applications include structural components, protective coatings, energy devices, and sensors. In structural uses, engineers may target strength with reduced weight; coatings can require tailored protection; energy devices and sensors can depend on controlled electrical behavior or responsiveness. Across these areas, the useful outcome comes from matching nanoscale chemistry and architecture to the required operating function.
Reactive Nanocomposites can be designed to combine multiple performance goals within one material system. Depending on the matrix, constituents, interfacial interactions, and reactions, they may provide improved mechanical strength, thermal stability, electrical behavior, barrier performance, or responsiveness while limiting material weight. This flexibility makes them relevant when reliability and controlled function must be achieved together.
