A　new　paint　which　can　absorb　a　large　amount　of　water　was　developed　for　restraining　frost　formation,　hydrophilic　surface　was　made　using　this　paint.　A　series　of　experiments　were　carried　out,　frost　thickness　and　frost　surface　temperature　were　measured　and　compared　on　the　hydrophilic　surface　and　metallic　surface,　and　the　main　factors　that　affect　frost　formation　on　hydrophilic　surface　were　studied.　Experimental　results　showed　this　kind　of　hydrophilic　surface　can　release　frost　growth　very　effectively,　the　onset　of　the　frost　formation　can　be　retarded　more　than　15　minutes　under　the　conditions　that　frost　formed　easily,　within　some　certain　conditions　below　the　freezing　point,　there　were　no　frost　crystals　formed　for　at　least　3　hours,　frost　thickness　greatly　reduced　by　40were　looser　and　stronger　on　the　hydrophilic　surface　than　on　the　metallic　surface,　and　thus　they　can　be　removed　by　external　force　more　easily.
