  Titan has a diverse range of materials in its atmosphere and on its surface:
the simple organics that reside in various phases (gas, liquid, ice) and the
solid complex refractory organics that form Titan's haze layers. These
materials all actively participate in various physical processes on Titan, and
many material properties are found to be important in shaping these processes.
Future in-situ exploration on Titan would likely encounter a range of
materials, and a comprehensive database to archive the material properties of
all possible material candidates will be needed. Here we summarize several
important material properties of the organic liquids, ices, and the refractory
hazes on Titan that are available in the literature and/or that we have
computed. These properties include thermodynamic properties (phase change
points, sublimation and vaporization saturation vapor pressure, and latent
heat), physical property (density), and surface properties (liquid surface
tensions and solid surface energies). We have developed a new database to
provide a repository for these data and make them available to the science
community. These data can be used as inputs for various theoretical models to
interpret current and future remote sensing and in-situ atmospheric and surface
measurements on Titan. The material properties of the simple organics may also
be applicable to giant planets and icy bodies in the outer solar system,
interstellar medium, protoplanetary disks, and exoplanets.
