We present a strategy to intrinsically moderate the electrostatic bond strengths in apolar polymeric solids by the covalent grafting of attenuator spacers to the charge carrying moieties. This produces a class of polyelectrolyte materials that have a charge density of 100%, are processable and ...
of chlorine to gain an electron, the elements are well suited to bond with one another. This transfer of electrons results in the formation of the ionic bond holding Na+and Cl–together. Ionic bonding is very common ininorganic chemistrybut is encountered much less frequently inorganic chemistry...
Ionic bondscan be very strong or very weak, depending on the size and electrical strength of the ions that make them up. However,ionic bondsare almost always very weak in liquids or in solids that dissolve in water. This is because the atoms are free to move around and can split from ...
Is CaCl2 a covalent or ionic bond? Is sodium chloride an ionic or covalent bond? Describe the bond that holds the atoms in a water molecule together. Will all combinations of metals and nonmetals form an ionic bond? How do a pure covalent bond, a polar covalent bond, and an ionic bond...
From rock salt to nanoparticle superlattices, complex structure can emerge from simple building blocks that attract each other through Coulombic forces1–4. On the micrometre scale, however, colloids in water defy the intuitively simple idea of forming c
Ionic compounds are usually soluble in water because water molecules are able to bond with both the positive and negative ions, which breaks up the lattice and keeps the ions apart. Review for previous lessons 1. What is the chemical bonding? It is an interaction between atoms or ions that ...

IL screening (based on the IL-miscibility database): To ensure no phase split occurs, the feasible IL candidates must be fully miscible in water(mole fraction of water,xw=1). ILs are likely to be miscible with thetarget solutewhen the two compounds have similar values of solubility parameter...
the phase-transition temperature does not change Polymer Journal Stimuli-responsive polymers in ILs T Ueki 650 substantially if methyl substitution is present at the 2-position of the imidazolium ring, a position that is known to possess strong hydrogen-bond-donating ability; 3. the phase-...
bond association, allowing for the continuous release of polymer strands to create topological entanglements as complementary crosslinks. By embodying properties of rapid stress relaxation, softness, ionic conductivity, self-healability, flaw-insensitivity, self-adhesion, and water-resistance, this ionic ...
