Investigation of antibacterial and wettability behaviours of plasma-modified PMMA films for application in ophthalmology

Fabrication and characterization of polymethylmethacrylate (PMMA) thin film by plasma polymerization used for cell culture

“…This can be caused by higher energy of impact by particles during deposition. In addition, the higher average deposition rate calculated from the thickness of deposited film is also likely to create more disordered surface of films [25,26]. For the oxygen treated surface, its roughness is even higher due to the oxygen implantation (thickening) and etching (thinning) on the surface.…”

Fabrication of TiO2 photocatalytic electrode and contamination control with atmospheric pressure O2 plasma jet

“…18 We diagnosed the atmospheric-pressure O 2 plasma jet with optical emission spectroscopy (K-MAC INC.) by changing the O 2 flow rate from 0 to 10 sccm under 500 sccm of He gas flow. 19 In addition, 0 sccm of O 2 gas flow also shows a peak at 777.4 nm, which may be due to ambient gas, such as oxygen in air. As shown in Figure 2, when we increased the oxygen flow rate from 0 to 5 sccm, the peak at 777.4 nm, which is assigned to reactive oxygen generated by plasma, was increased.…”

“…We think that increasing the oxygen gas flow rate in the plasma led to the significant decrease in the density of atomic oxygen, because it is attributed to the recombination of active species. 19 In addition, 0 sccm of O 2 gas flow also shows a peak at 777.4 nm, which may be due to ambient gas, such as oxygen in air.…”

The Influence of Pre‐Electrospinning Plasma Treatment on Physicochemical Characteristics of PLA Nanofibers

“…Plasma technology has a long history of several decades in polymer surface modification for various applications, of which biomedical uses are currently attracting more and more attention . Besides different polymer films, the surface of polymeric nanofibers, produced via electrospinning, have already been modified using plasma technology …”

“…DOI: 10.1002/mame.201900391 biomedical uses are currently attracting more and more attention. [1][2][3][4][5] Besides different polymer films, the surface of polymeric nanofibers, produced via electrospinning, have already been modified using plasma technology. [6][7][8][9][10] Attention and interest in nanofiber technology has substantially grown in the last decades due to their unique properties and many potential biomedical applications such as tissue engineering scaffolds, wound dressings, drug delivery devices as well as many other industrial applications.…”
