Background:

• Interpenetrating network (IPN) microgels offer unique properties due to their complex network structures.
• Understanding the synthesis-structure-property relationships is crucial for designing advanced functional materials.

Purpose of the Study:

• Analysis of polymerization kinetics and network interactions.
• Morphological studies in various solvent conditions (good, poor, selective).
• In silico investigation of shell-corona structure formation.

Main Results:

• Identified critical conditions for successful IPN microgel formation.
• Established correlations between synthesis parameters and microgel topology.
• Observed distinct microgel morphologies dependent on solvent quality.
• Demonstrated the novel formation of shell-corona structures in in silico synthesized IPN microgels under selective solvent conditions.

Conclusions:
