Prerequisites for Developing a Classification of Phase Transitions in Systems Based on Thermosensitive Polymers: Use...

Area of Science:

• Materials Science
• Polymer Chemistry
• Chemical Engineering

Background:

• Extensive experimental data on thermosensitive hydrogels and polymers requires organization.
• Existing data lacks a unified system for classifying behavior and phase transitions.

Purpose of the Study:

• To systematize and generalize existing experimental data on thermosensitive materials.
• To develop a novel classification system for thermosensitive hydrogels and polymer solutions.
• To propose a new semi-empirical theory for describing phase transitions.

Main Methods:

• Utilized the forward and reverse phase portrait method for data systematization.
• Developed a classification system based on the number of phase transition stages.
• Proposed a new semi-empirical model for phase transitions, relating them to chemical reactions.

Main Results:

• The phase portrait method effectively refines phase transition characteristics and enables classification.
• Phase transitions in thermosensitive systems can be described by equivalent first and second-order chemical reactions.
• The proposed model explains parabolic and linear dependencies observed in experimental phase portraits.

Conclusions:

• The developed classification and theoretical model provide a robust framework for understanding thermosensitive materials.
• This approach facilitates the automated systematization of thermosensitive polymer research using image recognition.
• The study establishes a foundation for advanced analysis and prediction of thermosensitive hydrogel and polymer behavior.
