ABSTRACT: In this paper, graphene@cuprous oxide (rGO@Cu2O)
nanocomposite was designed and prepared with graphene oxide, CuSO4,
NaOH and L-ascorbic acid via an in-situ reaction process, and the as-prepared rGO@Cu2O nanocomposite was
characterized by XRD, FT-IR, Raman spectroscopy, XPS, SEM-EDS and TEM. The
results reveal that the rGO@Cu2O nanocomposite is of homogeneous
distribution, and the Cu2O nanoparticles adsorbed on graphene sheets
are with a fairly uniform size of 2.3 nm. The rGO@Cu2O/acrylic resin
self-polishing marine antifouling paint with functional surfaces was also
prepared in this work, and a series of measurements were carried out for the
obtained product. The WCAs of paint is up to 113°, and the adhesive force is
averaged to 3.69 MPa. After being immersed into seawater, the whole bared panels
show an abundant growth of marine organisms within 90 days, but the rGO@Cu2O
paint coated surfaces are hardly fouled by marine organisms within 365 days. This
work demonstrates that in situ synthesis
of rGO@Cu2O is a tin-free potential alternative to inhibit
biofouling.
