    摘要: The embodiments herein relate to a benzoxazine resin composition, a prepreg, and a carbon fiber-reinforced composite material. More specifically, the embodiments herein relate to a benzoxazine resin composition that provides a carbon fiber-reinforced composite material that is suitable for use as a manufacture material due to its superior mechanical strength in extreme use environments, such as high temperature and high moisture, as well as a prepreg, and a carbon fiber-reinforced composite material. An embodiment comprises a benzoxazine resin composition having a multifunctional benzoxazine resin; a multifunctional epoxy resin that is a liquid at 40° C. and has three or more glycidyl groups; a sulfonate ester; and optionally at least one thermoplastic resin. The resin may include an interpenetrating network structure after curing.

    摘要: The present invention discloses blend polymer membranes comprising thermally rearranged polymers derived from aromatic polyimides containing ortho-positioned functional groups and methods for making and using these blend polymer membranes. The blend polymer membranes described in the current invention are prepared by heat treatment of blend polymer membranes comprising aromatic polyimides containing ortho-positioned functional groups such as —OH or —SH groups. In some instances, an additional crosslinking step is performed to improve the selectivity of the membrane. These blend polymer membranes have improved flexibility, reduced cost, improved processability, and enhanced selectivity and/or permeability compared to the comparable polymer membranes that comprise a single polymer.
