Hypothesis
Can whisker-toughened SiO2 aerogel improve the recycling process of waste polyurethane sheets?
Conclusion
The study found that whisker-toughened aerogel significantly enhances the mechanical properties and thermal stability of recycled polyurethane materials.
Supporting Evidence
- The whisker-toughened aerogel improved the viscosity of degraded polyurethane materials.
- The optimal compressive strength of the composite reached 817.93 MPa.
- The thermal conductivity of the recycled polyurethane foam was measured at 0.0228 W/(m·K).
- The study provides new methods for recycling waste polyurethane and developing thermal insulation materials.
Takeaway
This study shows how adding special whiskers to a type of gel can help recycle old foam materials into new, strong, and heat-resistant foam.
Methodology
The study used a sol-gel method to prepare SiO2 aerogel and tested its effectiveness in recycling waste polyurethane sheets.
