Method for predicting the rubber reinforcing effect of organic-inorganic composite for rubber reinforcement

A method for predicting a rubber reinforcing effect of an organic-inorganic composite, comprising:

• measuring weight change of an organic-inorganic composite as a function of temperature over a temperature range of 30° C. to 500° C. to perform thermogravimetric analysis (TGA);
• and
• determining if the organic-inorganic composite is sufficient for rubber reinforcement based on the following Equation 1 being satisfied:
• Da≥3.0 [Equation 1]
• wherein, in Equation 1,
• Da is an area under a derivative thermogravimetric curve over a temperature range of 300° C. to 500° C., wherein the derivative thermogravimetric curve is in units of weight reduction percent of the organic-inorganic composite relative to temperature (%/° C.), and
• wherein the derivative thermogravimetric curve is obtained from the thermogravimetric analysis (TGA) of the organic-inorganic composite.
