I did annealing of polyethylene of 200um(size 2x2 mm) on Silicon at 300 °C for 10 min. After the annealing process i saw the thickness of polyethylene increased to 500um approx!!!!!!
Can anyone explain why there is increase in the thickness of 200um to 500um of polyethylene????.
Dear colleague Dherru Kumar
Have a nice time and good day.
First, you have to check if the annealing temperature is suitable or not according to the DTA or DSC of your material.
Second, If the annealing temperature is high enough or near the melting point, the bonds may be broken and the disorder will increase though the material and the presence of pores will be increased so the resultant is the increasing of thickness.
I wish this is useful and help you.
Yours

Why would you have heated the polyethylene to 300 Celcius?? It has melted.
