Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Fire Retardancy

Background:

  • Polyurethane foam (PUF) is widely used but highly flammable.
  • Reducing PUF flammability is crucial for safety in applications like furniture and automotive interiors.

Purpose of the Study:

  • To develop an effective and environmentally benign coating to reduce PUF flammability.
  • To investigate the impact of a polyelectrolyte complex coating on PUF's structural integrity and fire performance.

Main Methods:

  • A two-step deposition process was used to apply a polyelectrolyte complex coating (polyethylenimine, ammonium polyphosphate, halloysite clay) onto PUF.
  • Electron microscopy was employed to analyze the coating's morphology and its effect on the foam structure.
  • Cone calorimetry was used to quantify the reduction in heat release rate.

Main Results:

  • The conformal thin film coating preserved the porous morphology of the PUF and increased its weight by 20%.
  • Coated PUF exhibited a 73% residue after direct flame exposure, maintaining structural integrity.
  • Cone calorimetry showed a 52.5% reduction in peak heat release rate (pkHRR) compared to uncoated foam.

Conclusions:

  • The developed polyelectrolyte complex coating effectively reduces PUF flammability.
  • The treatment is easy to apply, environmentally benign, and preserves the foam's essential porous structure.
  • This method offers a promising solution for enhancing fire safety in PUF applications.
