RNA Viruses - Coronavirus: New Study on High-Efficiency Antibacterial Fabric

Strategic Insights

— 2 min read

Researchers from Soochow University have developed a novel approach to create high-efficient antibacterial polypropylene spunbonded nonwoven fabrics (SNFs) decorated with a composite of graphene oxide embedded with silver nanoparticles (AgNPs/GO). This breakthrough has significant implications for personalized protection, especially under the backdrop of the COVID-19 pandemic. The study, published in the Journal of Applied Polymer Science, presents a facile method for decorating SNFs with a composite of AgNPs/GO, resulting in a high-performance antibacterial coating.

Key Takeaways:

  • The research team used a composite of graphene oxide embedded with silver nanoparticles (AgNPs/GO) to create high-efficient antibacterial polypropylene spunbonded nonwoven fabrics (SNFs).
  • The AgNPs/GO composite was introduced through a dip-coating and in situ reduction effect of pre-introduced amino-terminated hyperbranched polymer (HBP-NH2).
  • The treated SNFs exhibited excellent antibacterial activities (similar to 99.9%) against both Echerisia coli and Staphylococcus aureus.
  • The study was funded by the China Postdoctoral Science Foundation, Natural Science Foundation of Jiangsu Province, and the National Advanced Functional Fiber Innovation Center.
  • The research has significant implications for biomedical and personal protection applications, particularly under the COVID-19 pandemic.
  • The composite AgNPs/GO was uniformly dispersed on the GO nanosheets with a size of 13 nm.
  • The AgNPs/GO composite was capable of enhancing the thermal stability and mechanical property of SNFs.
  • The study used a facile approach to create high-efficient antibacterial polypropylene spunbonded nonwoven fabrics (SNFs).
  • The treated SNFs were able to exhibit excellent antibacterial activities (similar to 99.9%) against both Echerisia coli and Staphylococcus aureus.

Statistics:

  • 99.9% antibacterial activity against Echerisia coli and Staphylococcus aureus
  • 13 nm size of AgNPs uniformly dispersed on GO nanosheets
  • High-efficient antibacterial polypropylene spunbonded nonwoven fabrics (SNFs) created through facile approach
