PHB/PCL fibrous membranes modified with SiO₂@TiO₂-based core@shell composite nanoparticles for hydrophobic and antibacterial applications

Abstract

Schematic illustration of the synthesis of SiO2@TiO2-based core@shell composite nanoparticles (top) and antibacterial hydrophobic behavior of fibrous membranes (bottom).

Biocompatibility and Antimicrobial Activity of Electrospun Fibrous Materials Based on PHB and Modified with Hemin

“…Another important aspect of wound healing is the permeability to air [ 71 ]. The introduction of Hmi made a significant contribution to the control of the breathability of nonwoven fabric ( Figure 6 ).…”

Graphene quantum dots functionalised with rhamnolipid produced from bioconversion of palm kernel oil by Pseudomonas stutzeri BK-AB12MT as a photocatalyst

“…Meanwhile, TiO 2 synthesis followed the procedure reported by Lin et al with minor modification. 45 Then, 0.485 μL Tween-80 was added into 100 mL ethanol : H 2 O (19 : 1, v/v). Another solution containing 10 mL of TBT and 10 mL of ethanol was injected into the mixture of Tween-80, ethanol, and H 2 O at a rate of 0.5 mL min −1 and constant pressure using a funnel.…”

Fabrication of eco‐friendly superhydrophobic and superoleophilic PHB‐SiO2 bionanofiber membrane for gravity‐driven oil/water separation

“…Lin et al fabricated an electrospun PHB‐PCL nanofiber substrate to be used in packaging applications and modified the nanofiber surface with SiO 2 ‐TiO 2 composite nanoparticles produced by the stöber method. It was observed that the prepared PCL‐PHB/SiO 2 ‐TiO 2 composite membrane had excellent hydrophobicity and antibacterial activity with a water contact angle of 144° ± 1° 46 . In another study, PAN‐SiO 2 nanofibers were produced to be used in the separation of oil–water emulsion mixtures.…”

First, PAN nanofibers were produced and then the fibrous surface was modified with SiO 2 nanoparticles produced by the sol-gel method.…”
