Graphite thermal expansion
WebThe electrical conductivity of this material is graphite, but it can expand to more than 150 times. Therefore, suitable monomers, initiators, and macromolecules will be able to enter into voids, porosities, and interlayer spaces of expanded graphite to produce expanded polymer/graphite nanocomposites. WebThe linear thermal expansioncoefficient is the ratio change inlength per degree temperatureto length. Linear thermal expansion for some common metals: T(oC) = 5/9[T(oF) - 32]
