Chemical Vapor Deposition Based Superelastic and Superhydrophoboic Thermoplastic Polymeric Nanofibrous Aerogels for Water Purification

Developing high-performance, low-cost and large-scale absorbent materials is crucial for the treatment of water pollution caused by pollutants leakage emission. Herein, superelastic superhydrophobic thermoplastic polymeric nanofibrous aerogels (NFAs) were created removal from using a facile effective method. Poly(vinyl alcohol-co-ethylene) (EVOH) nanofibers fabricated mass-production techniques used to construct three-dimensional NFAs through combing freeze-drying process cross-linking treatment. The optimal parameters creating EVOH with good formability resilience, including composition ratio dispersion, dosage agent obtained experiments. bonded each other glutaraldehyde under acidic conditions fibrous network structure in NFAs. silane-coated prepared further modification vapor-phase methyltrichlorosilane. deposition siloxane improved mechanical strength decreased plastic deformation after 500 cyclic compressions. An asperate granular coating was deposited on surface contact angle increased 104.4° ± 4.0° 152.7° 1.9°, wettability transitioned being superhydrophobic. Silane-coated exhibited superior absorption capacity (40–92 g/g) variety organic pollutants. would be collected sorbents could reused distillation or squeezing. A successful scale-up such open up new insight into design substantial industrial purification applications.
