The conditions of our overpopulated planet with ever-growing energy
needs, fossil fuels in limited supplies, and inefficient energy use
world-wide, are creating a global crisis. Science has a
responsibility, as well as a grand opportunity, to solve these
energy-based problems of society. Science's new nanotechnologies,
and the creativity they bring, are particularly appropriate to
solve these problems. For example, energy-saving lighting, coupled
with improved harvesting and conversion of sunlight into electric
energy, will have a great impact on society's energy needs. Also,
development of energy efficient and low cost fuel cells, which
could eventually replace car engines, has a potential to improve
everyday life greatly. Nanomaterials offer an opportunity to
develop new low-cost materials as environmentally friendly
solutions and renewable energy sources, in order to meet society's
energy needs. Fortunately, a wide spectrum of the scientific
community has become interested in developing these nanomaterials
in order to solve the above energy challenges. Nanomaterials offer
unique mechanical, catalytic, electronic, and optical features,
which are different from those of the analogous bulk material (1).
This is because nanomaterials have scale-dependent properties, due
to quantum size effects, which means the nanomaterial size (10 -
100 nm) is smaller than the mean free path of their electrons.
Thus, nanomaterials have great promise for use in harvesting solar
energy, hydrogen production and storage, fuel cells, catalysis,
chemical, optical sensors, drug delivery systems (such as
liposomes), and nanothermite reactions (2-4). Fluorine-containing
nanomaterials generally have certain unique properties which are
often improved relative to the analogous non-fluorinated
nanomaterials, and which therefore could be engineered. Although
fluorine has the highest electronegativity of all the elements,
which means that bonds to fluorine are generally quite polar, it is
also in the second period of the periodic table, so it also has a
small atomic radius and forms strong bonds. This produces the
following properties, which also are characteristic of and bring
great advantages to fluorine nanomaterials: high thermal and
chemical stability, resistance to degradation by solvents, low
flammability, low moisture absorption, low surface tension or
energy, low dielectric constant, and serving as a strong oxidant
under high energy conditions (5). However, little attention has
been given to fluorine-containing organic and inorganic
nanomaterials, which are predicted to have these unusual
characteristics. This book presents examples of four diverse
classes of these nanomaterials.
