Promoting antibacterial performance of natural rubber latex
foam using a quinoline derivative
Abdulhakim Masaa, Sawitree Dueramaeb, Nabil Hayeemasaec,*
ABSTRACT: Natural rubber (NR) latex foam has been used in various products such as pillows, mattresses, and carpet
underlays, to name a few. Its cellular structure may lead to an easy growth of microorganisms. This may bring
harmful bacteria to the users. Therefore, this work aimed to develop antibacterial NR latex foam and offered the
basic formulation for preparing it. An antibacterial NR latex foam was prepared in the presence of quinoline derivative
namely 2-hydroxypropyl-3-piperazinyl-quinoline carboxylic acid methacrylate (HPQM). The use of HPQM influences
the physical characteristics and antibacterial activities. The clear zones of Staphylococcus aureus and Escherichia coli
increased over the HPQM content where a shorter contact time was used to kill the bacteria. The use of HPQM at
only 2 phr is sufficient to gain 100% killing efficiency in less than 2 h of contact time. This study offered resourceful
information in fabricating an antibacterial NR latex foam.
