Optical stereolithography of antifouling zwitterionic hydrogels

Abstract

This paper reports the rapid 3D printing of tough (toughness, <italic>U</italic>_T, up to 141.6 kJ m⁻³), highly solvated (<italic>ϕ</italic>^water ∼ 60 v/o), and antifouling hybrid hydrogels for potential uses in biomedical, smart materials, and sensor applications, using a zwitterionic photochemistry compatible with stereolithography (SLA).
