Photopolymerizable semicrystalline thermoplastics resulting from thiol-ene polymerizations were formed via fast polymerizations and achieved excellent mechanical properties. These materials have been shown to produce materials desirable for additive
Hypothesis Flocculation performance using polyelectrolytes is influenced by critical design parameters including molecular weight, amount and sign of the ionic charge, and polymer architecture. It is expected that systematic variation of these
Because of facile implementation, quantitative conversions, and an insensitivity to oxygen, water, and most organic functional groups, radical-mediated thiol–ene coupling (TEC) reactions have emerged as a valuable tool in macromolecule synthesis. It
Of importance for adhesive materials, particularly pressure-sensitive adhesive (PSA) systems, is the ability to increase bulk toughness without reduction of adhesion. Previous approaches for increasing PSA durability sacrifice permanent cross-
Objective Dental restorative composites have been extensively studied with a goal to improve material performance. However, stress induced microcracks from polymerization shrinkage, thermal and other stresses along with the low fracture toughness of
Objective To assess the performance ofÌýthiolÌýMichael photocurable composites based on ester-free thiols and vinylÌýsulfonamidesÌýof varyingÌýmonomerÌýstructures and variedÌýfillerÌýloadings and to contrast the
Despite the powerful nature of the aza-Michael reaction for generating C–N linkages and bioactive moieties, the bis-Michael addition of 1° amines remains ineffective for the synthesis of functional, step-growth polymers due to the drastic reduction
A phosphatidylcholine-based cerasome (PC-cerasome) was prepared by a combination of a copper-catalyzed azide alkyne cyclo-addition (CuAAC) reaction and a sol–gel condensation process. In a 2 wt % urea aqueous solution, azide precursors containing a
A new material developed by ¶¶ÒõÂÃÐÐÉäÌýBoulder engineers can transform into complex, pre-programmed shapes via light and temperature stimuli, allowing a literal square peg to morph and fit into a round hole before fully reverting to its original form
