In this paper

the preparation and application of paraffin-based/polymer

inorganic and polymer-inorganic hybrid shell microcapsules were mainly introduced

and the advantages and disadvantages of the above microcapsules were summarized. The wall materials of paraffin/polymer shell microcapsules include melamineformaldehyde resin

urea-formaldehyde resin

melamine-formaldehyde-urea resin

urethane resin

acrylic resin

etc

. The wall materials of paraffin-based/inorganic shell microcapsules include silica

titanium dioxide

calcium carbonate

and zinc oxide

etc

. The wall materials of the paraffin/polymer-inorganic hybrid shell consist of melamine-formaldehyde resin

melamine-formaldehyde-urea resin

acrylic resin

etc.

which are compounded with inorganic particles such as titanium dioxide and silicon dioxide. The future development direction and application prospect of paraffin-based microcapsule phase change materials have been prospected in order to provide a reference for future research.
