A polyurethane urea composition and a preparation method thereof are provided. The method includes mixing and reacting an urea and an amine compound to obtain a polyurea oligomer, and mixing and reacting the polyurea oligomer and a cyclic carbonate compound to obtain a polyurethane urea composition having a repeating unit represented by formula I:&#x2014;R&#x2014;U&#x2014;U&#x2014;U&#x2014;R&#x2014;, wherein &#x2003;&#x2003;[formula I]  

Polyurethane urea composition and preparation method thereof

A self-assembly coating material including carbon particles and polymer shells is provided. The polymer shells respectively cover and are bonded to the carbon particles, wherein each polymer shell has both a first functional group for adsorbing on a surface of a substrate and a second functional group for self cross-linking. The first functional groups include thiol groups. The second functional groups include epoxy groups or carboxylic groups. The self-assembly coating material can be applied to a metal substrate to form a heat dissipation layer.
