摘要： A method providing direct access to porous three-dimensionally (3D) continuous polymer network structures and shapes by combining BCP-resol co-assembly with CO2 laser-induced transient heating. The CO2 laser source transiently heats the BCP-directed resol hybrid films to high temperatures at the beam position, inducing locally controlled resol thermopolymerization and BCP decomposition in ambient conditions. This enables shaping of BCP-directed porous resin structures with tunable 3D interconnected pores in a single process. Pore size can be varied from 10 nm to about 600 nm.

摘要： A film comprising a crystalline halide perovskite composition having the following formula: AMX3 (1) wherein: A is an organic cation selected from the group consisting of methylammonium, tetramethylammonium, formamidinium, and guanidinium; M is at least one divalent metal; and X is independently selected from halide atoms; wherein the crystalline film of the halide perovskite composition possesses at least one of an average grain size of at least 30 microns, substantial crystal orientation evidenced in an ordering parameter of at least 0.6, and a level of crystallinity of at least 90%. Methods for producing films of these halide perovskite compositions using ionic liquids instead of volatile organic solvents are also described herein.
