Microcrystallization of Atactic Polystyrene Induced by Photooxidation Aging

open access: yesMacromolecular Materials and Engineering, 2023
Photooxidation aging, hygrothermal aging, and hot‐air aging are carried out on atactic polystyrene (aPS) samples formed by injection molding. It is interesting that microcrystals of atactic polystyrene are only found in photooxidation aging.

Hygrothermal and compressive mechanical behavior of composites plate with open-hole

open access: yesCailiao gongcheng
The mechanical properties of polymer matrix composites often decrease due to hygrothermal environment. The hygrothermal aging tests and the compression tests are carried out before and after aging on the T700/BP9916 composites plate with open-hole, and ...
