Abstract: S1.00074 : Tunable surface properties from bioinspired polymers
Author:
Anti-fouling properties can be derived from patterned or
``ambiguous''
surfaces displaying multiple surface properties. Biological
polymers with
precisely controlled chain shapes and self-assembled structures are
attractive materials for these applications, in which tunability
is of great
importance. We have investigated the surface properties of
polypeptoids, a
class of non-natural biomimetic polymers based on an
N-substituted glycine
backbone, that combine many of the advantageous properties of
bulk polymers
with those of synthetically produced proteins. Polypeptoids are of
particular interest as they can be made in a sequence controlled
fashion
with functionalities already known to impart fouling-resistance
(ethers,
zwitterions, hydrophobicity, and nanoscale patterning). We
demonstrate their
surface stability and processibility from the standpoint of coating
performance and also discuss controlled self-assembly of these
materials.
Used strategies include mediation of crystallization by
incorporating chain
defects and specific interactions.
