Water repellency of large-scale imprinting-assisted polymer films

We report that the water repellency of polymeric film surfaces can be simply tuned by pressing softened polymer films into porous anodized aluminum oxide (AAO) templates. Highly-dense nano-pillars and nano-hairs on the polymer surfaces are reproduced via physically or chemically separating the AAO templates from the impressed polymer films. The resulting polymeric nano-textures ...

Layer-by-layer assembly of graphene on polyimide films via thermal imidization and synchronous reduction of graphene oxide

To investigate the effects of holding time after deposition of polyethylenimine (PEI) solution and molecular weight of PEI on the surface morphology of multi-layer films prepared by layer-by-layer (LbL) method, polyamic acid (PAA)/PEI/graphene oxide (GO) films were prepared using different holding times and different molecular weights of PEI. To convert PAA into polyimide (PI), the ...



Influence of thermal aging on pyrolysis pattern of carbon black-filled NR composite

NR composites were aged at 60 oC for 10 to 185 days and the aged samples were pyrolyzed using pyrolysis-GC/MS. Isoprene, toluene, xylene, 1,4-dimethyl-4-vinylcyclohexene, and 1-methyl-4-(1-methylethenyl)-cyclohexene were detected as the major pyrolysis products. The 1,4-dimethyl-4-vinylcyclohexene and 1-methyl-4-(1-methylethenyl)-cyclohexene are the isoprene dimer species. Peak ...
