Summary
Liquid crystal polymers (LCNs) offer versatile actuation for soft robots but struggle in aquatic settings. This review explores LCNs in water, detailing challenges and future directions for underwater soft robotics.
Area of Science:
- Materials Science
- Robotics
- Polymer Chemistry
Background:
- Soft robots utilize compliant materials for enhanced dexterity and human interaction.
- Liquid crystal polymers (LCNs) are promising for soft robotics due to their stimulus-responsive and shape-morphing capabilities.
- Current LCN applications are limited in aquatic environments due to inefficient underwater actuation and complex water interactions.
Purpose of the Study:
- To review the relationship between water and LCNs.
- To survey literature on LCNs in aquatic soft robotic applications.
- To identify challenges and propose future strategies for LCNs in underwater environments.
Main Methods:
- Literature review of LCNs in aquatic soft robotics.
- Analysis of LCN-water interactions.
- Discussion of actuation methods and material properties in aqueous media.
Main Results:
- LCNs exhibit varied responses to water, impacting their performance in aquatic soft robots.
- Both hygroscopic and non-hygroscopic LCNs have been explored for underwater applications.
- Key challenges include actuation efficiency, material stability, and water compatibility.
Conclusions:
- Overcoming LCN-water interaction challenges is crucial for expanding their use in aquatic soft robotics.
- Further research into material design and actuation mechanisms is needed for robust underwater LCN applications.
- Successful adaptation of LCNs for aquatic environments will unlock new possibilities in underwater robotics.

Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.

Water and other polar molecules are attracted to ions. The electrostatic attraction between an ion and a molecule with a dipole is called an ion-dipole attraction. These attractions play an important role in the dissolution of ionic compounds in water.
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
