Fig. 5: Raman spectrum of PE and PVC at 1.0 wt% for validation.

Raman spectrum of mixture of PE 1.0 wt% and PVC 1.0 wt% with DI water. In the Raman spectrum of the mixture, the Raman bands of PE at 363 cm⁻¹, 637 cm⁻¹, 695 cm⁻¹, and 1432 cm⁻¹, as well as the Raman bands of PVC at 1062 cm⁻¹, 1129 cm⁻¹, and 1295 cm⁻¹, were all observed.
