Highly dispersible metallic acrylate composition, preparation method thereof and resin composition containing the same

A metallic acrylate composition prepared by a method comprising steps of:

• step (a):
• reacting an acrylic acid, a divalent metal oxide and a thermally conductive powder in a nonpolar solvent at a temperature ranging from 30° C. to 100° ° C.to obtain a first mixture;
• and
• step (b):
• removing the nonpolar solvent of the first mixture to obtain the metallic acrylate composition;
• wherein the metallic acrylate composition comprises:
• a metallic acrylate having a structure represented by Formula (I):
• wherein in Formula (I), M2+ is zinc ion, magnesium ion or calcium ion and R1 is a hydrogen group or a saturated alkyl group having 1 to 6 carbon atoms;
• and
• the thermally conductive powder including a graphene, a flake graphite or a combination thereof, and a content of the thermally conductive powder ranges from 0.3 wt % to 25 wt % based on the total weight of the metallic acrylate composition;
• wherein the graphene includes a reduced graphene oxide having carbon content more than 40% and 3 to 30 layers;
• and the flake graphite includes a flake graphite with carbon content more than 95%.
