The additive manufacturing of photopolymer resins by means vat photopolymerization enables the rapid fabrication bespoke 3D-printed parts. Advances in methodology have continually improved resolution and speed, yet both process design resin technology remained largely consistent since its inception 1980s
The remarkable elasticity and tensile strength found in natural elastomers are challenging to mimic. Synthetic typically feature covalently cross-linked networks (rubbers), but this hinders their reprocessability. Physical cross-linking via hydrogen bonding or ordered crystallite domains can afford reprocessable elastomers, often at the cost of performance. Herein, we report synthesis ultra-tough, based on linear alternating polymers. incorporation a rigid isohexide adjacent urethane...
Abstract Over the past 150 years, our ability to produce and transform engineered materials has been responsible for current high standards of living, especially in developed economies. However, we must carefully think effects addiction creating using at this fast rate will have on future generations. The way currently make use detrimentally affects planet Earth, many severe environmental problems. It next generations by putting danger economy, energy, climate. We are point where something...
Stereochemistry in polymers can be used as an effective tool to control the mechanical and physical properties of resulting materials. Typically, though, synthetic polymers, differences among polymer stereoisomers leads incremental property variation, i.e., no changes baseline plastic or elastic behavior. Here we show that stereochemical sugar-based monomers yield a family nonsegmented, alternating polyurethanes either strong amorphous thermoplastic elastomers with exceed most cross-linked...
Thiol–ene ‘click’ reactions between terpenes and a four-arm thiol were utilized to produced thermoset 3D printed structures using vat photopolymerisation.
The modern materials economy is inefficient since most products are principally derived from non-renewable feedstocks and largely single-use in nature. Conventional thermoset often inherently unreprocessable due to their irreversible covalent crosslinks hence challenging recycle and/or reprocess. Covalent adaptable networks (CAN)s, which incorporate reversible or dynamic bonding, have emerged as an efficient means afford reprocessable crosslinked increasing the feedstock sustainability of...
The development of photopolymers that can be depolymerized and subsequently re-cured using the same light stimulus presents a significant technical challenge. A bio-sourced terpenoid structure, l-carvone, inspired creation re-curable photopolymer in which orthogonal reactivity an irreversible thioether dynamic thiol-Michael bond enables both photopolymerization thermally driven depolymerization mechanically robust polymer networks. di-alkene containing l-carvone was partially reacted with...
Polymer crystallinity is known to be dependent upon backbone stereochemistry, and this concept has emerged as an effective means of altering bulk material properties. Herein we describe a simple, step-growth polymerization synthesize unsaturated poly(ester-urethane)s using the thiol-Michael addition reaction. The absolute control alkene stereochemistry (0–100% trans content) in polymer was achieved by varying cis/trans double bond content monomer feedstock. In turn, systematically varied...
Rigid ring structures have gained increasing interest in the polymer materials community as an effective means to manipulate bulk properties. Here, we investigate structure–property relationships of smallest ring: cyclopropane.
