Abstract

Phase-change materials have attracted more and more attention in the fields of both academic research and industrial application. To develop a simple, efficient and environment-friendly method for preparing polymer phase-change materials, microwave-assisted technology was employed to synthesis urea-formaldehyde phase-change microcapsules, with the core of dodecyl alcohol, the shell of urea-formaldehyde resin, the emulsifier of Span-80 and Tween-20. A few of key factors, such as emulsifiers, reaction temperature and time, can influence the thermal performance and the encapsulation. Finally, dynamic light scattering (DLS) and differential scanning calorimetry (DSC) were employed to characterize the size distribution, the phase transition temperature and latent heat. The results show that the size of urea-formaldehyde microcapsules is close to 1 ?m. And the urea-formaldehyde phase-change microcapsules have relative high phase-change latent heat storage capacity, 132.3 J/g and an encapsulation efficiency of 63.9%, respectively. Microwave-assisted technology has a bright future in the preparation of new-type polymer functional materials.
