Fluorosurfactants‐Directed Preparation of Homogeneous and Hierarchical‐Porosity CMP Aerogels for Gas Sorption and Oil Cleanup

Abstract

Homogeneous, hierarchical‐porosity and highly hydrophobic conjugated microporous polymer (CMP) aerogels are facilely prepared assisted by fluorosurfactants. The fluorosurfactants show several roles in controlling the gelation process, modulating pore structures, and raising the hydrophobicity of materials, thus giving rise to aerogels with exceptional gas sorption and oil cleanup performance.

A Review of Femtosecond‐Laser‐Induced Underwater Superoleophobic Surfaces

“…Oil/water separation technology has become a global challenge to protect the environment and reduce economic loss . Recently, various meshes or porous materials with special wettability (such as superhydrophobicity or superoleophobicity) have been successfully used in oil/water separating application owning to the different interface effect between water and oil . In 2004, Feng et al fabricated a superhydrophobic–superoleophilic mesh by coating polytetrafluoroethylene (PTFE) rough microstructures onto stainless steel mesh surface .…”

“…Aerogels are al arge class of self-supported porous materials with virtually unlimited compositions ranging from silica, polymers,n anocarbons,a nd semiconductors to met-als. [1][2][3][4][5][6][7] Especially for the recently emerging noble-metal aerogels (NMAs), their combined features,i ncluding selfsupported architectures,h igh specific surface areas,3 D electron/mass transfer pathways,a nd numerous optically/ catalytically active sites,h ave endowed them with broad application prospects such as in electrocatalysis,s urfaceenhanced Raman scattering, and sensing. [8][9][10] However,since their discovery in 2009, [11] the development has been quite slow,w hich is presumably due to the great challenges encountered by the material fabrication.…”

Semiconducting Conjugated Microporous Polymer: An Electrode Material for Photoelectrochemical Water Splitting and Oxygen Reduction

“…Motivated by these possibilities, an effort is undertaken to synthesize and study the band structure properties of CMP namely, poly(1,3,5‐triethynylbenzene) (PTEB) network, (see Figure a) comprising phenyl rings linked by diacetylene bonds. To the best of our knowledge, PTEB network has so far been studied for their applications in superabsorption (CO 2 and CH 4 ), oil‐water separation and hydrogen gas storage . However, photophysical and electrochemical properties of PTEB networks are hitherto unknown.…”
