In recent years, functionalized hydrophobic materials have attracted considerable interest as oil removal agents. This investigation has applied plasma polymerization a novel method to develop and oleophilic particles for water purification. 1,7-Octadiene was polymerized onto silica using radio frequency inductively coupled reactor fitted with rotating chamber. Plasma 1,7-octadiene (ppOD) films were deposited power of 40 W monomer flow rate 2 sccm, while time varied from 5 60 min. The...
Highly negatively charged particles were fabricated via an innovative plasma-assisted approach for the removal of heavy metal ions. Thiophene plasma polymerization was used to deposit sulfur-rich films onto silica followed by introduction oxidized sulfur functionalities, such as sulfonate and sulfonic acid, water–plasma treatments. Surface chemistry analyses conducted X-ray photoelectron spectroscopy time-of-flight secondary ion mass spectroscopy. Electrokinetic measurements quantified zeta...
Abstract Conductive fibers are needed for the development of flexible electronic and biomedical devices. MXene show great promise use in such applications because their high conductivity. Current literature on fiber highlights need improving mechanical properties investigation biocompatibility. Here silk fibroin biopolymer as a formulation additive production is studied. It found that favorable fibroin–MXene interactions resulted improved durability, withstanding up to 1 h frequency...
Current synthetic bioceramic scaffolds often lack bioinstructive ability for effective bone regeneration. We have selected magnesium-doped baghdadite (Mg-BAG) scaffolds, known their promising osteoinductive and mechanical properties, as the base material fabricated them using a liquid crystal display 3D printing technique. Building on this foundation, we advanced application of ion-assisted plasma polymerization (IAPP) technology, adapted structures, to develop homogeneous interfaces these...
The chemical surface modification of carbon fibers has been a prolific area literature in recent years, but little done to translate these advances short discontinuous fibers. Routinely used as fillers composite materials, the prospect using improve performance milled carries appeal. This work describes adaptation conventional electrochemical reduction aryl diazonium salts recycled and explores improvements mechanical achieved therein simple epoxy resin system. Increasing fiber mass loadings...
Abstract The outstanding electrical conductivity and high specific capacitance of 2D Ti 3 C 2 T x MXene have made them promising materials for a wide range applications including wearable electronics, energy storage, sensors, electromagnetic interference shielding. However, the fabrication architectures, both pure composite, often results in trade‐off properties. Here, it is reported that sequential bridging sheets significantly enhances mechanical properties its free‐standing films, with...
Thermal oxidation of porous silicon (pSi) has been used to control interactions with three proteins; lysozyme, papain, and human serum albumin (HSA) enabling the influences protein structure, molecular weight, charge be elucidated. Adsorption behavior was assessed via adsorption isotherms while structures adsorbed proteins were investigated using a bioactivity assay, FTIR, zeta potential. Time-of-flight secondary ion mass spectrometry examine pore penetration. High onto unoxidized pSi...
1,7‐Octadiene (OD) was plasma polymerised onto silicon wafers and glass slides under a broad range of input specific energies deposition times to study the hydrophobicity deposited films. Deposition 1,7‐octadiene (ppOD) film resulted in decrease slide surface free energy (SFE) from ≈71 44 mJ · m −2 . X‐ray photoelectron spectroscopy (XPS) time flight secondary ion mass (ToF‐SIMS) results confirmed that this is due concealing polar SiOH groups by non‐polar C x H y functionalities. Atomic...
