Polynorbornene glass transition temperature
WebA lithium-ion battery comprising an anode, a cathode, a lithium-ion permeable and electrically insulating separator that electrically separates the anode from the cathode, and an artificial solid-electrolyte interface (SEI) layer disposed between the anode and the separator wherein (a) the artificial SEI layer has a lithium-ion conductivity greater than 10 … Web458. BLOCK COPOLYMERS. Vol. 1. A standard notation for block copolymers is becoming accepted, whereby X-b-Y denotes a diblock copolymer of polymer X and polymer Y. However, sometimes the b is replaced by the full term block, or alternatively is omitted, and the diblock denoted X–Y.. A number of texts covering general aspects of block copolymer science and
