Title: DEVELOPMENT OF IMPROVED AND NOVEL THERMAL CONTROL COATINGS (Preprint)
Abstract: Abstract : Thermal control coatings (TCCs) play a critical role in the thermal management of space assets through the reflection of incident solar energy and emittance of infrared heat. The development of new thermal control coatings with improved solar energy reflection, infrared emittance, and reduced weight are essential to the design of future space assets that will reside in harsh environments and have increasing constraints on weight. Optimization of pigment particle size and type can play an important role in the development of improved coatings. Recent improvements in the synthesis and particle size control of zinc orthotitanate pigment for silicate binder coatings have resulted in performance improvements over prior coatings of this type as well as the current zinc oxide based coatings. In addition, a novel pigment concept based on hollow silica particles is continuing to be explored as an extremely space durable and lightweight option for passive thermal control coatings.
