Understand The Structure-Water-Responsive Relationship by Engineering Silk Materials
<p>Water-responsive (WR) materials mechanically swell and shrink in response to changes in relative humidity, and they have demonstrated the capability to exert higher actuation energy than conventional actuators and artificial muscles. As a result, WR materials have recently gained attention as …

Temperature and Water Responsive Shape Memory Polymers for Soft Tissue Expansion
… that these polymers showed temperature and water responsive shape memory properties i.e., these could be programmed to recover back to their original shape when brought in contact with external stimuli (temperature and water). This is based on the transition of these polymers from the glassy …

Biomimetic Water-Responsive Structures: From Fundamental Mechanisms to Evaporation Energy Harvesting Applications
<p>Biological systems have developed remarkable water-responsive (WR) structures that deform in response to changes in relative humidity (RH) and convert evaporation energy (chemical potential of water) to mechanical energy. For example, the scales of pinecones open and release pine seeds when the …

The Effect of Nanoconfined Liquid Properties on the Water-Responsive Behavior of Bacterial Cell Walls
<p>Water-responsive (WR) materials have the ability to mechanically swell and shrink in response to changes in relative humidity (RH). These WR materials are used by many biological systems to perform essential tasks; for example, pinecones use WR materials to release their seeds in dry …

Shape changing composite material design for interactions
… embodiment. Two major projects exemplify how water-responsive shape-changing material can be used to design interactions based on the outlined design strategy. bioLogic is about hygromorphic bacteria-based SCMC, while Transformative Appetite is about water-driven edible SCMC material. …

Process-Structure-Property Relationships of Cellulose Derivative/Thermoplastic Urethane Polymer Composites
… behavior, mechanical performance, and water-responsive properties. Through a series of three integrated studies, the evolution of these composites from solvent-cast films to fully extrudable, AM-compatible filaments is established. In Chapter 3, an HPC/TPU blend system was fabricated …

4D-Printing with Cellulose Nanocrystal Thermoplastic Nanocomposites: Mechanical Adaptivity and Thermal Influence
… window for 3D printing of mechanically responsive composites and the influence of temperature on mechanical adaptivity, thermal stability, and rheology. CNC thermoplastic nanocomposites are a water responsive, mechanically adaptive material that has been gaining interest in additive …

Application-oriented development of thermoplastic polyurethanes with shape memory properties
… shape memory effect” (2W-SME). This thermoresponsiveness makes them highly interesting for the use as system components in e.g. programmable materials. Programmable materials act self-sufficiently, combining sensory and actuation properties in a single material. Thus, SMPs are providing the …
