NOVELTY - Making a shape conforming material, comprises: providing a shape memory material having a glass transition temperature; adding a selected amount of heat transfer nanoparticles to the shape memory material to provide the shape conforming material.    USE - The method is useful for: making a shape conforming material; and forming an apparatus for use in a wellbore (all claimed).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) forming an apparatus for use in a wellbore (110), comprising providing a shape conforming material that contains a base shape memory material having a glass transition temperature and a selected amount of heat transfer nanoparticles, where the heat transfer have a core and a shell and forming a device for use in the apparatus that includes the shape conforming material;    (2) an apparatus for use in wellbore, comprising a device having a shape memory member that includes a base shape memory material having a glass transition temperature and a selected amount heat transfer nanoparticles, where each nanoparticle includes a shell and a core in it that is configured to melt within the shell to store heat energy, and where the shape conforming material in the device is in a compressed shape obtained by compressing the shape conforming material from an expanded shape at or above the glass transition temperature;    (3) a system for use in a wellbore, comprising a string containing a tubular and a device for performing an operation in the wellbore, where the device includes a shape conforming member that includes a base shape memory material having a glass transition temperature and a selected amount heat transfer nanoparticles, each nanoparticle includes a shall and a core therein that is configured to melt within the shell to store heat energy, and the shape conforming material in the device is in a compressed shape obtained by compressing the shape conforming material from an expanded shape at or above the glass transition temperature; and    (4) making a shape conforming device, comprising providing a base material that expands when exposed to a heated fluid, adding a selected amount of heat transfer nanoparticles to the base shape memory material to provide a shape conforming material, and using the shape conforming material to form the shape conforming device.
