Investigations of the thermal properties of fatty acids as energy stor
age materials (ESMs) have been proceeding for some time. Several of th
ese, when incorporated into building materials such as wallboard, have
proved efficacious for absorbing and releasing heat as ambient temper
ature rises and falls. This makes them potentially useful for suppleme
ntal cooling and heating applications. Unfortunately other properties
of these materials such as flammability, odor and smoke production mak
e them undesirable for construction use. This study using DSC and flam
mability testing describes some new candidates for ESMs which avoid so
me of these inherent problems; in addition to providing greater energy
storage capacity.
