Abstract

In this paper, transparent elastomers were prepared by increasing the degree of branching and introducing fluorinated structures, and their property changes were systematically investigated. The results showed that the mechanical strength and barrier capacity of the materials increased significantly as the degree of branching increased. In particular, the mechanical strength increased from 0.136 MPa (P300CS) to 1.848 MPa (PCTE₃). With the introduction of fluorinated structures, the water vapor transmission rate decreased from 36.3 g/(m²·day) (P300CS) to 16.8 g/(m²·day) (PCTE₃F_c). Therefore, this material has a promising application in the field of electronic packaging.
