The thermo-optical properties of coated surface are important for spacecraft thermal control coatings which depend on the optical properties and structure of the coating material. These coatings control the temperature by their capability of outer energy absorption and its emission. The optical properties of pigment can be improved if the pigment contains a high fraction of voids in its structu...
this paper presents an investigation on the effect of temperature and raw material on microstructure of fine cellular foam used as the insulation of coaxial cables. a set up was prepared and used to produce fine cellular foamed insulation. as the physical blowing agent, butane was used. the effect of temperature on the microstructure of polyethylene (pe) was worth to note. at high temperature,...
