Formation of Polycyanoacrylate−Silica Nanocomposites by Chemical Vapor Deposition of Cyanoacrylates on Aerogels

Fabrication of honeycomb-patterned polyalkylcyanoacrylate films from monomer solution by breath figures method

“…It was because that the small hydro- philic -OH heads of the long chain did not have strong interaction with water. And it was hard for the disarrayed hydrophobic PACA [49,50] to adopt a conformation which would allow transporting sufficient -OH heads to be anchored at the water-chloroform interface during the quick evaporation process. As a result, there was no enough PACA to aggregate into polymer layer to envelop the water droplets, consequently coalescence of the water droplets took place and irregular pores were obtained on the resultant films.…”

Polyaniline nanofiber–silica composite aerogels

“…If aerogels are going to be used, they must be strong enough to withstand being manipulated without breaking apart into shards and powder [7]. We have previously addressed the inherently weak mechanical properties of silica aerogels by using rapid, chemical vapor deposition of chlorosilane monomers [8] or cyanoacrylate monomers onto aerogels [9,10] and surface-initiated atom transfer radical polymerization [11] of methyl methacrylate onto the surface of the gels before drying to afford silica aerogel-PMMA composites. Others have strengthened silica aerogels by introducing cross-linked epoxy resins [12], styrenes [13], and isocyanates [14,15] by polymerizations conducted in the gels before drying.…”

Superhydrophobic polyethylcyanoacrylate coatings. Contact area with water measured by Raman spectral images, contact angle and Cassie–Baxter model

“…Li et al [15] prepared hollow microspheres of poly(ethyl-a-cyanoacrylate) via vapor-phase polymerization using micro-water droplets as templates and initiators, which were used to construct surfaces with diverse wettability. Boday et al [16] modified glass slides with polycyanoacrylate (PECA) by chemical vapor deposition and measured water contact angles of 129°. Troitskya et al [17] developed a method of hydrophilic/hydrophobic patterning of solid surfaces based on polycyanoacrylate monolayers with water contact angles of 102-103° [18].…”
