cross-link

Thân thiện

A scientist points to a cross-link in a diagram of a polymer chain.

Definition

1. Noun:

   • A side bond that links two adjacent chains of atoms in a complex molecule: In chemistry, a "cross-link" is a bond that connects one polymer chain to another, increasing the material's strength and stability.

2. Verb:

   • To join by creating covalent bonds (of adjacent chains of a polymer or protein): The action of forming these connecting bonds between polymer or protein chains.

Usage Examples

• Noun:

  • The durability of the rubber is due to the cross-links between its polymer chains.
  • Scientists studied the protein's structure by analyzing its cross-links.

• Verb:

  • The chemical process is designed to cross-link the polymer chains, making the plastic more rigid.
  • These agents can cross-link adjacent proteins, altering their function.

Advanced Usage

• "To become cross-linked": Describes the state or process of forming cross-links.
  • Over time, the collagen in skin can become cross-linked, leading to reduced elasticity.

Variants and Related Words

• Cross-linked (adj): Describes a material that has undergone the process of cross-linking.
  • Cross-linked polyethylene is used for high-temperature piping.
• Cross-linking (n): The process or phenomenon of forming cross-links.
  • The cross-linking of the gel was observed under the microscope.

Synonyms

• Noun: Bridge, interconnection, bond.
• Verb: Interconnect, bridge, bond.

Related Phrases

• Cross-link density: A measurement of how many cross-links exist in a given volume of a polymer.
  • The material's properties change with its cross-link density.
