Manipulation of phase transition temperatures and supercooling of sugar alcohols based Phase Change Materials (PCMs) by urea
Conference contribution, 2016

In this work we have investigated the possibility to change the thermal characteristics of the sugar alcohols erythritol and mannitol by use of urea as additive. The results show that even small amounts of urea have a great influence on the thermal properties of the sugar alcohols, which in turn implies large structural differences between the different compositions. For both sugar alcohols both smaller and higher fractions of urea result in two melting peaks, whereas a eutectic composition is obtained at intermediate urea fractions. However, not all compositions undergo crystallization on cooling.
