Povidone-iodine enhanced underwater tape

Area of Science:

• Adhesion science
• Biomaterials
• Polymer chemistry

Background:

• Achieving stable adhesion in humid conditions is difficult for current wound dressings and underwater adhesives.
• Existing materials often fail under wet conditions, limiting their application in medical and industrial settings.

Purpose of the Study:

• To design and synthesize a polyacrylate-based underwater tape with water-enhanced adhesion and antimicrobial capabilities.
• To address the limitations of current adhesives in wet environments for applications like wound dressings.

Main Methods:

• Synthesized a polyacrylate-based tape using 4-hydroxybutyl acrylate (4-HBA) and isobornyl acrylate (IBOA) as comonomers.
• Incorporated povidone iodine (PVP-I2) as a reinforcing filler and antimicrobial agent.
• Evaluated underwater adhesion, mechanical properties, and antimicrobial efficacy.

Main Results:

• The synthesized tape demonstrated good underwater adhesion, attributed to hydrogen bonding from 4-HBA and structural stability from IBOA.
• PVP-I2 addition provided tunable mechanical properties and significant antimicrobial activity.
• The material maintained cohesion strength effectively under water.

Conclusions:

• A facile method for preparing a wet adhesive with excellent underwater adhesion and antimicrobial properties was developed.
• The polyacrylate-based tape shows promise for applications in wound dressing and as underwater adhesive materials.
