Functionalization of Biodegradable PLA Nonwoven Fabric as Superoleophilic and Superhydrophobic Material for Efficient Oil Absorption and Oil/Water Separation

Abstract

Although the construction of superwettability materials for oil/water separation has been developed rapidly, the postprocess of the used separation materials themselves is still a thorny problem due to their nondegradation in the natural environment. In this work, we reported the functionalization of polylactic acid (PLA) nonwoven fabric as superoleophilic and superhydrophobic material for efficient treatment of oily wastewater with eco-friendly post-treatment due to the well-known biodegradable nature of PLA matrix.

Compatibilization of polypropylene/poly(glycolic acid) blend with maleated poe/attapulgite hybrid compatibilizer: Evaluation of mechanical, thermal, rheological, and morphological characteristics

“…In recent years, as the growing environmental awareness and shortage of natural resource, biodegradable and biobased polymer materials have received significant interest in numerous areas as a substitute of conventional petroleum‐based manufacture . Such as poly(lactic acid) (PLA), polycaprolactone (PCL), and their blends or composites, have been deeply explored and applied for several decades . Poly(glycolic acid) (PGA), as a kind of aliphatic polyester with a similar macromolecular structure to PLA, has been mainly used in biomedical engineering such as suture material due to its excellent mechanical properties, biocompatibility, and predictable biodegradation via hydrolysis into natural metabolic waste products .…”

Polypropylene Nonwoven Fabric@Poly(ionic liquid)s for Switchable Oil/Water Separation, Dye Absorption, and Antibacterial Applications

“…[1,2] However the constituents of wastewater,i ncluding oils, [3][4][5] dyes, [6][7][8] and bacteria, [9,10] are usually complex, making wastewater cleanup difficult. [21][22][23] Therefore, preparing smart oil/water separation materials with switchable wetting behaviorh as received attentionb ecause it involves a simple low-energy process with high separation efficiency.F or example, Xue and co-workers fabricated superamphiphilic PVDF membrane with switchable transport performance. Oil/water separation techniques have attracted attention to address environmental concerns caused by the leakage of industrial organic pollutants and oils into the aquatic environment.…”
