Ureasil-polyether hybrid film-forming materials

Area of Science:

• Materials Science
• Biomedical Engineering
• Polymer Chemistry

Background:

• Film-forming systems are crucial for various applications, including skin and wound protection.
• Developing novel materials with enhanced properties like biocompatibility and adhesion is an ongoing challenge.

Purpose of the Study:

• To evaluate the suitability of cross-linked ureasil-polyether hybrid matrices as film-forming systems.
• To highlight the advantages of these hybrid matrices over existing commercial products.

Main Methods:

• Rheological measurements were used to assess film formation time.
• Water Vapor Transmitting Rate (WVTR) was measured to determine semi-occlusive properties.
• Biocompatibility and bioadhesion were evaluated, with a focus on the role of amine groups.

Main Results:

• Ureasil-polyether hybrid matrices demonstrated excellent film-forming capabilities, producing thin, transparent films rapidly.
• The films exhibited significant bioadhesion, surpassing that of commercial adhesives.
• Adequate semi-occlusive properties (WVTR) suggest suitability for skin and wound protection.
• The presence of multiple amine groups in the hybrid molecules enhanced both skin bioadhesion and non-cytotoxic character.

Conclusions:

• Cross-linked ureasil-polyether hybrid matrices are highly suitable as film-forming systems.
• These materials offer advantages in biocompatibility, cosmetic appearance, rapid film formation, and superior bioadhesion.
• The developed films show promising potential for applications in skin and wound protection due to their properties and non-cytotoxic nature.
