Area of Science:

• Materials Science
• Polymer Chemistry
• Actuator Technology

Background:

• Traditional polyvinyl chloride (PVC) gel flexible actuators suffer from high input voltage requirements and inadequate elastic modulus.
• Addressing these limitations is crucial for advancing the performance and applicability of polymeric gel actuators.

Purpose of the Study:

• To investigate the properties of PVC gel modified with polyvinyl chloride-vinyl acetate (P(VC-VA)).
• To compare the modified PVC gel with traditional PVC gel regarding dielectric constant, mechanical modulus, and electromechanical actuation.
• To assess the potential of this novel plasticization method for engineering applications.

Main Methods:

• Preparation of modified PVC gel incorporating P(VC-VA).
• Characterization of dielectric constant, mechanical modulus, and electromechanical actuation performance.
• Application of the Gent model to analyze experimental electromechanical data.

Main Results:

• The introduction of P(VC-VA) significantly enhanced the dielectric constant of PVC gels from 4.77 to 7.3.
• Driving electric field strength was reduced, and electromechanical actuation performance increased by 150%.
• Experimental data showed good agreement with the Gent model, validating the material's behavior.

Conclusions:

• The P(VC-VA) plasticization method effectively balances the mechanical and electrical properties of PVC gels.
• This innovative approach offers a promising solution for developing high-performance flexible actuators.
• The modified PVC gels exhibit potential for diverse engineering applications requiring advanced polymeric materials.
