Abstract: Phosphorus-modified siloxanes monomer DOPO-IPDI-AMEO (DIA) was synthesized and characterized by (1)H nuclear magnetic resonance (H NMR), (31)P NMR, and Fourier transform infrared spectra (FTIR). It hydrolyzed and grew an organic-inorganic hybrid coating on the surface of cotton fabrics via sol-gel process. The conversion of gel reaction was characterized by solid-state (29)Si NMR. The effect of the modified organic-inorganic hybrid materials on thermal properties of cotton fabrics was investigated by thermogravimetric (TG) analysis, real time Fourier transform infrared (RT-FTIR), and microscale combustion calorimetry (MCC) experiments. In addition, thermogravimetry-Fourier transform infrared spectra (TG-FTIR) were used to investigate the released degradation products. The characterization information represented that DIA has been prepared successfully. Also the conversion of gel reaction was fairly high. The TG data showed that char residues increased with the addition of the DIA coating. While the peak heat release rate (PHRR) decreased with the presence of the coating in MCC test. Moreover, the flammable degradation products dropped obviously, which can be observed from the data of TG-FTIR.
