| Summary: | 碩士 === 國立臺灣大學 === 材料科學與工程學研究所 === 87 === The research of nano-composite was the popular subject in the past few years . We tried to disperse montmorillonite in epoxy and hoped to synthesize the nano-composite
Montmorillonite was constructed from silicate layers and was difficult to disperse in organic monomers , so we have to organize it. We observed the adsorption of montmorillonite as it was organized. And then we can know the adsorption curve of montmorillonite . All amines we selected to organize montmorillonite are short-chain ones because we hope that it can improve the interaction between montmorillonite and epoxy .
When samples were constructed , we performed a lot of experiments .It was found that adding the montmorillonite would decrease the mechanical properties of samples , except some samples of adding the montmorillonite was organized by ethyldiamine and diethyltriamine . For the thermal properties , the glass transfer temperature will increase and activity energy will decrease when adding more montmorillonite in the sample.
