Alterations in swelling percentage, mechanical, and thermal characteristics of polyacrylamide hydrogel under varying Table initial pressures through molecular dynamics simulation

Key Points

• Swelling percentage of polyacrylamide hydrogels increases with initial pressure, indicating altered properties.
• Mechanical properties significantly vary, with a noted increase in tensile strength at higher pressures.
• Using molecular dynamics simulation, interactions among polymer chains are assessed under varying conditions.
• Findings encourage exploration of pressure effects in hydrogel applications, particularly in biomedical fields.
