Figure 4. (A) XRD spectra of CPCM, (B) Static contact angles of flame retardants and CPCM samples. Error bars represent the standard deviation (SD) of five repeated measurements performed for each sample, Schematic diagram of the migration effect of (C) PADM3, (D) PAD@M3. CPCM: Composite phase-change material; MCA: melamine cyanurate; APP: ammonium polyphosphate; AD: ammonium polyphosphate and dipentaerythritol; XRD: X-ray diffraction; PEE: PEG2000/ER/EG; PAD@M: PEG2000/ER/EG/AD@MCA.
