“…However, PLA has some drawbacks, such as low thermal resistance and low flexibility [ 3 , 4 , 5 , 8 ] and is easily colonized by fungi and bacteria [ 9 ]. Therefore, strategies to enhance its mechanical and antibacterial properties [ 10 , 11 ] are required for the commercial utilization of these polymers and for broadening their scope of application while maintaining their biodegradable and ecofriendly properties.…”

A novel method was used to synthesize a nanosilver-doped multiwall carbon nanotube (MWCNT-Ag), and subsequently, the novel poly(lactic acid) (PLA)-and MWCNT-Ag-based biocompatible and antimicrobial nanocomposites were prepared by melt blending. Based on energy dispersive X-ray spectrometry images, an MWCNT-Ag was successfully synthesized. The effect of the MWCNT-Ag on the PLA bionanocomposites was investigated by evaluating their thermal and mechanical properties, antifungal activity, and cytotoxicity. The nanocomposites exhibited a high degree of biocompatibility with the MWCNT-Ag content, which was less than 0.3 phr. Furthermore, tensile strength testing, thermogravimetric analysis, differential scanning calorimetry, and antibacterial evaluation revealed that the tensile strength, thermostability, glass transition temperature, and antibacterial properties were enhanced by increasing the MWCNT-Ag content. Finally, hydrolysis analysis indicated that the low MWCNT-Ag content could increase the packing density of PLA.

“…Herein, the grafting of MDAA was efficient at a higher temperature; the grafting ratio was extremely low at room temperature. The optimal grafting temperature was 80 °C, as reported in our previous study …”

“…These peaks that disappeared were replaced by new peaks of aliphatic ether (2934/2883/1451/1412 cm –1 ) and aliphatic secondary or primary alcohol (1183/1106/1041 cm –1 ). This might be due to the degradation of the PP nonwoven caused by the H 2 SO 4 catalyst during the PG process at 80 °C . The oxirane ring of MDAA opened to aliphatic secondary or primary alcohol, and then it reacted with PP to produce C–O–C aliphatic ether (1183/1106 cm –1 ).…”

“…MDAA has functional groups (oxirane group and π bond) and quaternary ammonium groups that impart excellent antibacterial and hydrophilic properties. MDAA was grafted onto a PP nonwoven through a traditional PG process (Scheme a) . Although plasma is an excellent polymer-processing method, most plasma processes require a long time for grafting purposes.…”

A conventional plasma grafting (PG) process for surface treatment has limitations; thus, it should be modified to boost its efficiency. In this study, a new process called immersion−pad-pressing−drying−plasma (IPDP) was proposed. We applied IPDP to graft a quaternary methyl diallyl ammonium salt on the surface of a polypropylene (PP) nonwoven. Ar and O 2 were used as carrier gases for the plasma treatment. For this IPDP process, the optimum acid catalyst concentration was established to be 0.2 M. The grafted PP exhibited excellent antibacterial and hydrophilic properties. Because of the introduction of more peroxides or carboxylic acid groups into the PP nonwoven, the graft ratio for the PG and IPDP processes with O 2 as the carrier gas was demonstrated to be higher than that for the processes with Ar as the carrier gas. The finished PP fabric obtained using the IPDP process indicated antibacterial and hydrophilic properties superior to those of the fabric obtained from the traditional PG process. The IPDP process could overcome the disadvantages of the conventional plasma process, one of which is that the PG process requires a long period of time to bring a grafting reaction to completion. This new IPDP process is shown to be an efficient technique for industrial applications.

“…[ 91 ] Whereas the nonpolar chains of QAS/PS interact with the nonpolar, inner part of cytoplasmic membranes, the positive charges on the groups interact with the polar outer part of the membranes, disrupting the electrical and osmotic balance and other important functions of the cell to culminate in bacteriolysis. [ 92 ] QASs have been plasma‐grafted on different surfaces, namely polypropylene, [ 93 ] glass fiber membranes, [ 94 ] and polyethylene foils [ 95 ] to impart antibiofouling properties.…”

Plasma processing finds widespread biomedical applications, such as the design of biosensors, antibiofouling surfaces, controlled drug delivery systems, and in plasma sterilizers. In the present coronavirus disease (COVID‐19) situation, the prospect of applying plasma processes like surface activation, plasma grafting, plasma‐enhanced chemical vapor deposition/plasma polymerization, surface etching, plasma immersion ion implantation, crosslinking, and plasma decontamination to provide timely solutions in the form of better antiviral alternatives, practical diagnostic tools, and reusable personal protective equipment is worth exploring. Herein, the role of nonthermal plasmas and their contributions toward healthcare are timely reviewed to engage different communities in assisting healthcare associates and clinicians, not only to combat the current COVID‐19 pandemic but also to prevent similar kinds of future outbreaks.
