Sustained free chlorine-releasing polydimethylsiloxane/Ca(ClO) materials with long-lasting disinfection efficacy
A novel sustained chlorine-releasing polydimethylsiloxane/Ca(ClO) 2 (PDMS/Ca(ClO) 2 ) material was fabricated by encapsulating Ca(ClO) 2 in a PDMS matrix due to its high hydrophobicity and high chemical stability, which showed immediate-responsive and long-lasting antibacterial capabilities in aqueo...

| description | A novel sustained chlorine-releasing polydimethylsiloxane/Ca(ClO)
2
(PDMS/Ca(ClO)
2
) material was fabricated by encapsulating Ca(ClO)
2
in a PDMS matrix due to its high hydrophobicity and high chemical stability, which showed immediate-responsive and long-lasting antibacterial capabilities in aqueous conditions. Free chlorine could be released from the PDMS/Ca(ClO)
2
after immersion in water for 2 min and could also be sustainedly released for 2 weeks, while the released concentration is negatively related to the duration time and positively with the initial Ca(ClO)
2
contents. Additionally, Ca(ClO)
2
powder as a filler significantly affects the crosslinking and pore size of PDMS. The PDMS/Ca(ClO)
2
materials exhibited enduring antibacterial performance against
Escherichia coli
(
E. coli
) and
Staphylococcus aureus
(
S. aureus
) in both planktonic and multispecies-biofilm status. It is expected that this PDMS/Ca(ClO)
2
material and its similar composite would be promising candidates for wide sustainable disinfection applications in biomedical and industrial fields.
The article introduces a new PDMS/Ca(ClO)
2
material that releases chlorine over two weeks, effectively combating bacterial growth, and suggesting versatile applications in biomedical and industrial disinfection. |
