Formvar film was generally used as supporting material of the DT filled ICF target or as basementmaterial in XRL experiment.It's needed to establish a fabrication method which is not only rapid andsimple but also able to control accurately the film thickness,The present pull-out-from-solution methodfits these requirements very well.Various technological problems such as the effects of temperature,concentration(C)and the pull-out speed on thickness and uniformity was investigated.Results showsthe temperature is a major factor concerning the film uniformity.The film thickness(d)dependsmainly on the solution concentration:d=aC￣a+b,where a、b、a are constants.
