Prompt Gamma Activation Analysis of Impurity and Elemental Stability for Two SU-8 Organic Polymer Samples Having Different Solidification Pretreatment

ABSTRACT

In this paper, two samples of SU-8, a photo polymer consisting of Gamma-Butyrolactone (GLB) mixed with both Triarylsulfonia and Hexafluroantimonate considered for a Prompt Gamma Activation Analysis (PGAA) diagnostic study. The SU-8 was formed into two organic polymer microturbines which were then given different solidification pretreatment using varying durations of heat baking and Ultra-Violet (UV) crosslinking. In addition to determining the major components of the analyzed samples, some trace elements were also identified, and all the compositions were compared. The measurements were performed at the Budapest Research Reactor (BRR). The obtained results have advanced the industrial applicability of the adopted technique in the considered sector of polymer analysis, because the PGAA has been applied in the case of the polymer of the microturbines. The results obtained are complementary to data achieved by other techniques
