From a product-type viewpoint, flexible
polyvinyl chloride (PVC) and poly(urethane)-foam-based
applications have used biocides for decades.[8,9] PVC is
especially vulnerable to attack from fungi and bacteria
due to extensive plasticizer usage in flexible applications.[
10] Poly(urethane) foams are another notable consumer
of biocides because of their porous nature, which pro-
vides an ideal environment for microbes to grow.[11,12]
Therefore, it is not surprising that many applications
based on these two materials have significant usage of
biocides; commonly, oxybisphenoxarsine or lower toxic-
ity alternatives such as zinc pyrithione (ZPT) antimicro-
bials are employed.[10] Specific example applications
include kitchen and bath accessories, swimming pool
liners, carpet backing, sleep solutions like mattresses and
pillows, roofing membranes, and tiles.
To reduce the incidence of device-associated infections,
antimicrobial technologies have been utilized in a variety
of ways ranging from bulk-imbedded additives to sur-
face grafting techniques.[13,14] In particular, silver-based
additive technologies are frequently explored for
healthcare applications due to their favorable toxicological
profiles and broader regulatory approvals, while silver
nanoparticles with controlled, long-term release profiles
continue to be a very active and promising area of biomedi-
cal research.[15-19] In textile segments such as sports active-
wear, biocides are used to prevent the growth of odor-
causing bacteria from perspiration.[20,21] Additionally,
high-end recreational products such as boats utilize bio-
cides to preserve the aesthetics of PVC products used for
seat covers since bacterial growth may lead to pink staining
caused by specific bacterial metabolites.[22,23] With respect
to the mechanism of action, many antimicrobial products
work by attacking enzymes common to a variety of
microbes, interfering with membrane transport processes
(e.g., importing environmental copper into the cells) as
well as interfering with iron metabolism pathways.[24,25]
Herein, an assortment of both rigid and flexible resins/
compounds will be evaluated for susceptibility to determine
whether particular resin chemistries or compounds are
inherently vulnerable to microbial growth and subsequent
degradation or other deleterious effects.
