A LATP/LAGP bi-layer structured solid electrolyte has been prepared via a simple dry-pressing and post-calcination process, which exhibits high electrical conductivity and excellent stability in air as well as high chemical stability against Li.

We present the fabrication of superhydrophobic surfaces by electrospraying structure controlled poly(methyl methacrylate-bromine) (PMMA-Br) homopolymer and degree of fluorination controlled poly(methyl methacrylate)-b-poly-(dodecafluoroheptyl methacrylate) (PMMA-b-PDFMA) copolymers synthesized via atom transfer radical polymerization (ATRP). The flow rate has great effects on the surface hydrophobicity of PMMA 50.6 , and superhydrophobic surface was obtained at a higher flow rate of 5 μL/min. For fluorinated diblock copolymers, superhydrophobic surfaces can be obtained by electrospraying PMMA 50.6 -b-PDFMA 0.8 and PMMA 147.9 -b-PDFMA 17.5 at the selected flow rates. X-ray photoelectron spectroscopy (XPS) detections reveal that, during the film formation, more hydrophobic surfaces would be fabricated due to the surface segregations of C−C and C−H groups with THF as solvent instead of C−O−CO group with DMF as solvent. This investigation may be of great value in fabricating superhydrophobic polymer materials.
