Quadruple Shape-Memory Organohydrogels with Adjustable Trigger Temperatures.

ABSTRACT: Organohydrogels (OHGs) are a class of soft materials with a biphasic structure consisting of hydrophilic and hydrophobic domains that interact with both water and organic solvents. This gives them unique properties and various applications, e.g., in biomedicine, antifreeze, soft robotics and environmental engineering, where adaptability and resilience are crucial. In the present work, we present OHG systems consisting of a continuous hydrogel phase based on silk fibroin (SF) in which single, binary or ternary combinations of semicrystalline poly-(n-tetradecyl acrylate) (PC14A), poly-(n-hexadecyl acrylate) (PC16A) and poly-(n-octadecyl acrylate) (PC18A) micro-organogels with side chain lengths between 14 and 18 are dispersed. The OHGs withstand 90-94% compression without failure and have a
