Thin polymer films whose thickness ranges from fractions of a nanometer to several micrometers have been in high demand over the past few years in several industries. Their high surface area to volume ratio and the potential for low-cost processing with minimal material usage while fulfilling purpose requirements make them very useful. However, these films behave differently from bulk materials and majority of polymer fabrication processes involve polymer flow. Hence the study of polymer thin film rheology becomes crucial. Bulk measurement of rheology is well established, but it has disadvantages in that it requires a lot of material and may not capture thin film physics. Previous studies have demonstrated dewetting of thin polymer films to study film material stability and properties. This study seeks to use focused laser spike (FLaSk) dewetting as a method to probe rheology of thin material films. The method is used to extract materials properties of three thin films – Polystyrene (PS), Poly –4–hydroxystyrene (PHS) and N, N′-Bis (3 – methylphenyl)–N, N′-diphenylbenzidine (TPD) having different glass transition temperatures,
