Synthesis and Characterization of Graphene Oxide (GO) and Reduced Graphene Oxide (rGO) for Gas Sensing Application
Tập 376 Số 1 - 2017
In the present investigation, GO was prepared by exfoliation of graphite using
modified Hummer's method and then reduced using hydrazine hydrate (reducing
agent) to produce rGO. XRD, FESEM, Raman, FTIR spectrophotometer and TGA were
used for characterization of GO and rGO. XRD images reveal crystalline structure
for both GO and rGO. The d‐spacing is observed to be reduced for rGO as compared
to th...
Aerocellulose: Aerogels and Aerogel‐like Materials made from Cellulose
Tập 244 Số 1 - Trang 126-135 - 2006
AbstractSummary: Cellulose aerogels have been prepared starting from
cellulose‐NMMO solutions via the classical aerogel‐path. Different cellulosic
materials have been tested and their influence on the properties of the product
aerogels has been studied. Other parameters that have been varied include
solution composition as well as the way of cellulose regeneration (solvent and
temperature). More t...
Bioprocessing – no longer a field of dreams
Tập 201 Số 1 - Trang 271-282 - 2003
AbstractA Field of Dreams was a movie about baseball. The theme was “Build it
and They Will Come.” Bioprocessing as an industry has been waiting for someone
to step up to the plate and build a large business, based on the technology. The
large business was necessary to bring about a revolution to move the Chemical
and Plastics Industries towards a new business model, based on more sustainable
prac...
Surface modification of polymers: Physical, chemical, mechanical and biological methods
Tập 101 Số 1 - Trang 443-454 - 1996
AbstractThe principal objectives and methods of surface modification of polymers
are reviewed in this paper. The techniques covered include physical, chemical,
mechanical and biological methods.
1. History of CA and evolution of the markets
Tập 208 Số 1 - Trang 1-6 - 2004
AbstractAn overlook is given of the 100 years of technical, industrial and
chemical development of cellulose acetate. CA has been used as raw material in
the fields of laquer, plastics, textile, Filter Tow, film, membrane and others.
In the field of applications for plastics and textiles CA was quite successful
for many years, but was then slowly substituted by other polymers. Total
cellulose acet...
3. Acetate manufacturing, process and technology 3.1 Chemistry of cellulose acetylation
Tập 208 Số 1 - Trang 49-60 - 2004
AbstractNowadays Celluloseacetate is mainly produced with the acetic acid
process. After an activation with acetic acid and sulfuric acid the acetylation
of the cellulose starts by adding acetic anhydride. The temperature and the
catalyst concentration play an important role for the reaction. Beneath
acetylation also degradation of the cellulose chains occurs. In the first step
of the process cell...
Preparation, Characterisation and Properties of Nanocomposites Based on Epoxy Resins – An Overview
Tập 221 Số 1 - Trang 127-136 - 2005
AbstractAn overview about the use of nanoparticles in epoxy resins is given.
Deaggregated fumed silica, sol gel materials and other spheroidic nanoparticles
improved the abrasion resistance and the mechanical properties of filled
epoxides, and several properties can be improved by specific particles.
Combustion properties, strength and permeation can be improved by organically
modified layered sil...
Percolation in carbon black filled epoxy resin
Tập 104 Số 1 - Trang 261-268 - 1996
AbstractThe conditions to form a conductive network in carbon black filled epoxy
resin were examined. It was found that the formation is controlled by
particle‐particle interaction which can be influenced by shear forces or by the
ionic concentration of the resin. Therefore the network morphology and thus the
percolation threshold depends strongly upon the processing route. On best
conditions the ...
Syntheses and properties of syndiotactic polystyrene
Tập 89 Số 1 - Trang 553-562 - 1995
AbstractSyndiotactic polystyrene (SPS) is a new crystalline engineering
thermoplastic. With a melting point of 270 °C and its crystalline nature, SPS
has high heat resistance, excellent chemical resistance and water/steam
resistance. Since SPS has excellent dielectric properties, it is useful as a
capacitor insulation material. The rate of crystallization is very fast in
comparison with isotactic ...
Synthesis and Characterization of Sulfonated‐ Fluorinated, Hydrophilic‐Hydrophobic Multiblock Copolymers for Proton Exchange Membranes
Tập 245-246 Số 1 - Trang 439-449 - 2006
AbstractNanophase separated ionic‐hydrophobic block copolymers may be more
suitable as proton exchange membranes than random copolymers. A series of
multiblock copolymers, composed of alternating segments of fully disulfonated
poly(arylene ether sulfone) and highly fluorinated poly(arylene ether sulfone),
were synthesized from hydrophilic and hydrophobic telechelic oligomers having a
variation of ...
