Characteristics and Nomenclature of Copolymers

2.6K
Copolymers are the products obtained from the polymerization of multiple monomer species. So, in a polymer chain itself, there can be multiple repeating units that come from different monomers. The process of synthesizing a polymer from different monomer species is called copolymerization. When two monomers are involved, the polymer is known as a bipolymer. Polymers with three and four monomers are termed terpolymers and quaterpolymers, respectively. Figure 1 depicts the copolymerization of...

Cationic Chain-Growth Polymerization: Mechanism

2.4K
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the...

Area of Science:

  • Polymer Science
  • Materials Science
  • Computational Chemistry

Background:

  • Block copolymer (BCP) self-assembly is crucial for creating nanostructured materials.
  • Understanding the kinetic pathways of BCP particle formation is essential for controlling their final morphology.

Purpose of the Study:

  • To explore the dynamic structural evolution and formation pathways of block copolymer particles.
  • To investigate the kinetic paths leading to various particle morphologies like striped ellipsoids, onion-like, and double-spiral lamellar structures.

Main Methods:

  • Dynamic self-consistent field theory (DSCFT) was employed to simulate the self-assembly process.
  • Analysis focused on the influence of temperature and solvent selectivity on particle morphology.

Main Results:

  • Process-directed self-assembly in a poor solvent yields striped ellipsoids, onion-like, and double-spiral lamellar particles.
  • Reversible shape transitions between onion-like and striped ellipsoidal particles were predicted by tuning temperature and solvent selectivity.
  • A kinetic pathway involving onion-like to double-spiral lamellar and back to onion-like particles was demonstrated.
  • Formation of striped ellipsoidal particles requires transitioning from a bi-continuous to a layered structure.
  • Onion-like particle formation involves a two-stage microphase separation: solvent-induced followed by thermodynamic control.

Conclusions:

  • The study provides insights into the kinetic control of block copolymer particle morphology.
  • Findings enable effective tailoring of BCP particle nanostructures for industrial applications.
  • The theoretical framework allows for predicting and controlling shape transitions through external parameters.
