| Abstract: | The reaction extent of organic phase,as well as the degree of hydrolysis and condensation reactions of inorganic phase of polyurethane material,was examined by means of 1H-NMR.The results show that the hydrogen-bond forms between the shell material polyurethane and the core material silicon dioxide.The organic phase and the inorganic phase are compounded to steady particles which have core/shell structure. |
