▎ 摘　　要

NOVELTY - Preparing microcapsule, comprises (i) mixing active group modified-carbon nanomaterial, furancarboxylic acid or its derivatives and first organic solvent, and performing esterification reaction to obtain esterified carbon nanomaterial, (ii) mixing first microcapsule wall material, furancarboxylic acid or its derivatives and second organic solvent, and performing esterification reaction to obtain esterified microcapsule wall material, (iii) mixing esterified carbon nanomaterial, esterified microcapsule wall material, bismaleimide and third organic solvent and reacting to obtain microcapsule wall material intermediate, and (iv) mixing microcapsule wall material intermediate, second microcapsule wall material raw material, flavoring agent and solvent, reacting, and filtering to obtain final product. USE - The microcapsule is useful in cigarette products (claimed). ADVANTAGE - The microcapsule improves heat conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for microcapsule obtained by above method, where the heat-conducting coefficient of microcapsule is 0.30-0.45 W/m.k.
