We developed a method to quantify polymer entanglement complexity in condensed phases. This approach analyzes subchains within a cube, assessing entanglement based on density and subchain count.

Area of Science:

  • Polymer Physics
  • Computational Chemistry
  • Materials Science

Background:

  • Understanding polymer entanglement is crucial for predicting material properties.
  • Condensed phase polymers exhibit complex topological interactions.

Purpose of the Study:

  • To develop and present a method for quantifying polymer entanglement complexity.
  • To analyze entanglement as a function of monomer density and subchain number.

Main Methods:

  • Monte Carlo simulations of polymers in a condensed phase.
  • Modeling a system of k self-avoiding and mutually avoiding walks within a cube.
  • Assessing entanglement complexity of subchains intersecting a defined cubic volume.

Main Results:
