Structures of Solids

18.9K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Phase Transitions: Melting and Freezing02:39

Phase Transitions: Melting and Freezing

15.3K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Metallic Solids

21.0K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Polymers

41.5K
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Network Covalent Solids02:18

Network Covalent Solids

16.3K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Molecular and Ionic Solids02:54

Molecular and Ionic Solids

20.3K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Summary

Adsorbed polymer chain structure significantly impacts adhesion. Loosely adsorbed polymer chains act as connectors, enhancing adhesion, while flattened chains show no adhesion, revealing key interfacial structure-property relationships.

Area of Science:

  • Polymer Science
  • Surface Chemistry
  • Materials Science

Background:

  • Understanding polymer-surface interactions is crucial for materials design.
  • Physisorption of polymer chains creates complex interfacial structures.
  • Adhesion properties are highly dependent on the nanoscale arrangement of adsorbed polymers.

Purpose of the Study:

  • To investigate the relationship between the interfacial structure of adsorbed polymer chains and their adhesive properties.
  • To compare the adhesion of "flattened" versus "loosely adsorbed" polymer chains.
  • To elucidate the molecular mechanisms behind adhesion differences.

Main Methods:

  • Creating two distinct adsorbed polymer chain conformations (flattened and loosely adsorbed) of polyethylene oxide (PEO) on silicon substrates using Guiselin's approach.
  • Conducting adhesion tests on bilayers using a custom-built device.
  • Utilizing neutron reflectivity experiments to analyze interfacial structure.
  • Performing coarse-grained molecular dynamics simulations to model interfacial interactions.

Main Results:

  • Flattened PEO chains exhibited no adhesion with a top PEO overlayer.
  • Loosely adsorbed PEO chains demonstrated significant adhesion.
  • Neutron reflectivity ruled out interfacial broadening as the cause of adhesion differences.
  • Molecular dynamics simulations indicated that the tail parts of loosely adsorbed chains act as "connector molecules".

Conclusions:

  • The interfacial nanostructure of adsorbed polymers dictates adhesive properties.
  • Loosely adsorbed polymer chains enhance interfacial adhesion by bridging free chains and the substrate.
  • Precise control over interfacial polymer nanostructures offers a pathway for developing advanced sticking and anti-sticking technologies.
