使氧化

The dispersion mechanism of the dispersants was analyzed by testing the Zeta potential of the dispersion phase in the dispersion medium. It was shown that Ⅰ and Ⅱ raised obviously the absolute values of surface Zeta potential of titania particles, and NK-1 formed good solvate layers of the particles so that the nano-titania particles were stably dispersed in the water solns.

The photodegradation rate of M-PPV 1 was constrained by DABCO that quenches the triplet state of M-PPV; 2increased when the solvent changed from benzene to deuterated benzene in whichthe lifetime of triplet state is longer than that in benzene; 3 was improveddramatically with high concentration of M-PPV triplet state was generated by energytrasfer from biacetyl.

发现：1能猝灭M-PPV的三重态的1，4-二氮二环[2.2.2]辛烷也能有效地抑制光氧化反应的进行；2能提高M-PPV三重态寿命的氘代溶剂也能使M-PPV光氧化降解速率加快，3丁二酮和M-PPV间的能量传递能够提高M-PPV三重态的浓度，这和丁二酮作三重态敏化剂敏化光氧化M-PPV时，M-PPV的光降解速率大大增加也是一致的。
