摘要：
In this study, CA-based derivative (CA, CAP, CAB)/PEG films were prepared using Breath Figure Array (BFA) method, and the surface void characteristics of films formed by the types of CA, CAB, and CAP, as well as films with PEG formulation, were analyzed. For this purpose, the chemical properties of CA-based derivatives were compared, and CA-based derivative/PEG films were prepared using BFA method using a blade coater. The changes in pore size, arrangement, and uniformity were compared via FE-SEM on the film surface according to the type of CA-based derivative and the presence or absence of PEG addition. FT-IR results confirmed the differences in CA, CAP, and CAB due to the fatty acid chain length. TGA results showed that CA showed relatively high thermal stability. In the films with the addition of PEG, both CAP and CAB showed narrower pore size distributions and more uniform pore arrangements. © 2024 Korean Technical Assoc. of the Pulp and Paper Industry.
