Stable carbonized microspheres can readily be obtained with highly efficient char yields of close to 60% from photopolymers based on photo-induced Diels-Alder step growth polymerizations α-methoxy benzaldehyde and bismaleimide precursors. The current study carefully elucidates the chemical decomposition pathways during pyrolysis that yield excellent via thermogravimetric analysis (TGA) infrared (IR) spectroscopy. high low shrinkage 33% make Diels-Alder-type a promising system for next...
Abstract Photopolymer derived carbon grows in popularity, yet the range available feature sizes is limited. Herein, focus on expanding field to low surface volume ratio (SVR) structures. A high temperature acrylic photopolymerizable precursor with FTIR and DSC described a thermal inert‐gas treatment developed for producing architected mm scale SVR of 1.38×10 −3 µm −1 . Based thermogravimetric analysis mass spectrometry, two regimes activation energies ≈79 169 kJ mol are distinguished, which...
Foils made from elastomeric polymers, such as polycarbonate-based polyurethane (PCU), can combine desirable properties including flexibility, durability, and compliance. Still, their usage is often limited by strongly autohesive behavior. To overcome this issue, surface coatings be applied. Here, dopamine-based (dopa) carbodiimide-mediated (carbo) are compared assessing tribological performance after long-term sliding tests, storage or sterilization. Even though both coating strategies...
Today, Atomic Layer Deposition (ALD) sets the limits for achieving nanometer precision of thin, yet almost dense films. However, initial growth process, determining possible film thinness, is poorly understood. A better understanding can be obtained with help in-situ characterization during high spatial and chemical resolution. Transmission Electron microscopy (TEM) would a suitable widely available technique to accomplish this objective. standard instruments have differing vacuum...
With unprecedented freedom in materials design, additive manufacturing (AM) technologies provide us with the capabilities to leverage from geometric complexity. If properly exploited, this allows design performance instead of geometry, where latter is not user defined but a result computer optimization. Entirely new mathematically defined, dimensionally stable carbon are presented that shrink isotopically under pyrolysis process generating complex CAD 3D shapes theoretically two three orders...
