dispersibility and thermalstability too.
The above products were characterized by FT-IR, XRD, Raman, SEM, TEM and TG. The results show that two nanohybirds have been fabricated successfully and the thermal stability of the nanohybirds was improved in comparison with GO observably. Moreover, the degree of the thermal stability of nanohybirds was improved was different at different temperatures. The higher the reaction temperatures were, the more the degree of thermal stability of nanohybirds were improved in a certain range of temperature. Beyond the range, it shows the opposite pattern. On the whole, the law curve presents normal distribution and exists maximum optimal value. Also, the dispersibility of GO-MA and MA-mGO nanohybirds was improved in comparison with pure GO which can be dealt with solution treating, and simplifying the multifarious steps during the preparation of composites. The achivements in this thesis will provide a certain amount of data to support and practical experiences for some application fields, such as flameresistant material.
