Preparation and Characterization of CMC/Melamine Resin Nano-encapsulated Phase Change Energy Storage Materials
摘要
Abstract
Nanocapsulated phase change materials were prepared by in-situ polymerization, using melamine-formaldehyde resin modified by carboxymethyl cellulose （CMC） as the shell and phase change material paraffin as the core. The properties of the products were studied by FTIR, SEM, DSC, and optic microscope, and the influences of the emulsifier sort and stirring rate of paraffin emul- sion preparation on the preparation process of phase change capsules were investigated. The results showed that the phase change cap- sules prepared with anionic emulsifier and nonionic emulsifier are superior to those prepared with simple emulsifier. The performance of paraffin emulsion is optimal when the stirring rate is 8000 r/min in the preparation process of paraffin emulsion. The phase enthalpy of the phase change nano-capsules is 81.87 J/g and the average particle size is about 50 nm with full wrap and uniform size.关键词
