DESCRIPTION:Speakers: Aline SIMO (PHD Student)\nExamples of novel coating 
 technologies towards Infrared solar radiation regulation/modulation in sma
 rt glass windows for the satellite sector include electrochromic and therm
 ochromic based high vacuum manufactured dynamic coatings. The latter two t
 echnologies are solar radiations control oriented technologies in the visi
 ble and infrared radiation respectively. The thermochromic smart coated wi
 ndows are infrared active and self regulating systems. Due to its natural 
 phase transition around 68°C\, vanadium dioxide coated systems exhibit an
  exceptional reversible and self induced optical modulation in the infrare
 d solar spectrum. If the temperature of the vanadium dioxide coated on a g
 lass window is smaller than 68°C\, the smart window is transparent to the
  solar infrared radiations i.e. heat transmitting while it reflects the in
 frared radiations if its temperature is higher than 68°C i.e. heat opaque
 . To apply such a thermochromic smart material on a large scale in automot
 ive and building sector\, it is required to shift their transition tempera
 ture to about 25°C as well as innovating a physical-chemical process for 
 production of large surface coatings. While the first requirement can be a
 chieved by tungsten doping\, the second could be reached by a hybrid polym
 er- VO2 (M) nanoparticles based coatings. This contribution reports the ph
 ysical and specifically the optical characteristics of VO2 nanoplatelets/P
 VP nano-composites.\n\nhttps://events.saip.org.za/event/7/contributions/49
