Preparation and Characterization of Modified Montmorillonite/Paraffin Phase Change Microcapsules for Energy Storage
The phase change microcapsules of modified montmorillonite/paraffin were prepared by Pickering emulsion method. Analytic techniques of optical microscopy, scanning electron microscopy(SEM), infrared spectroscopy(FTIR), differential scanning calorimetry(DSC) and thermogravimetry(TG) were utilized for...

The phase change microcapsules of modified montmorillonite/paraffin were prepared by Pickering emulsion method. Analytic techniques of optical microscopy, scanning electron microscopy(SEM), infrared spectroscopy(FTIR), differential scanning calorimetry(DSC) and thermogravimetry(TG) were utilized for characterizing chemical structure, morphology and thermal properties. Results show that modified montmorillonite as a new type wall material has excellent performance for protecting core material of paraffin. FTIR spectra of phase change of modified montmorillonite/paraffin microcapsules shows that their characteristic peaks match with corresponding peaks of pure paraffin and modified montmorillonite. DSC results indicate that modified montmorillonite/paraffin microcapsules have similar solid-liquid phase change temperature with pure paraffin.
