“…Homo-polymerisation has been achieved using γ and UV radiation, free-radical initiators, pyridine bases, and electrochemical initiation 4–6. Copolymers of maleic anhydride and its isomeric acids (or ester derivatives) have been formed with a wide variety of monomers, such as styrene,7, 8 vinyl chloride,9, 10 and acrylic acid 2. Often the experimental set-up required to produce conventional maleic anhydride homopolymers and copolymers is extremely expensive and requires installation of specialised or high-pressure instruments 11.…”

Maleic anhydride plasma polymers enable amine containing biomolecules and polymers to be covalently coupled to a surface from an aqueous solution without any intermediate chemistry. The challenge in developing these functionally active plasma polymers lies in determining the optimal deposition conditions for producing a stable, highly active film. Unlike many previous studies that explore highly varied pulsed and continuous wave (CW) deposition conditions, this paper focuses on the comparison of films deposited under the same low nominal power conditions (1 W) and compares a range of CW, ms and µs pulsing parameters that can be used to produce this power condition. The use of attenuated total reflectance -Fourier transform infra red spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) has enabled the quantitative examination of the effects of processing parameters on the chemical functionality of the films. For the first time, the molecular specificity, surface sensitivity and high mass resolution of time-of-flight static secondary ion mass spectrometry (ToF-SSIMS) has been exploited to compare these films and multivariate analysis techniques used to explore the relationships between plasma processing parameters and surface chemistry. The results of the studies clearly demonstrate that a range of conditions can produce maleic anhydride films, with optimal functionality seen under µs pulsing regimes. Critically, the study demonstrates that the tight control and monitoring of the deposition parameters is critical if these films are to be manufactured with optimal functionality, stability and minimum processing time.

“…MA is an interesting material for the synthesis of thin films due to the double bond and the reactive anhydride group [5][6][7]. Many techniques can be used to polymerize MA through conventional methods [8,9], however, they require expensive equipment, the use of chemical solvents and reaction times may be too long. There exist previous studies on the chemical structure and properties of MA films deposited through conventional plasma processes [6,7,[10][11][12][13][14].…”

Maleic anhydride film deposition through an active screen plasma system

The active screen plasma system has been extensively studied over the past few years, mainly for plasma nitriding purposes. This technique also provides possibilities of treating non-electrical conducting materials, such as polymeric ones, which is unattainable with a conventional DC plasma system. In this work, an active screen plasma setup for maleic anhydride (MA) film deposition on a glass substrate was used. The plasma working gas was a mixture of argon and MA vapour. Films obtained through conventional plasma discharge were compared with the active screen deposition process, in both DC and pulsed-mode plasma. The samples were characterized through Fourier-transform infrared spectroscopy and static contact angle between the film's surface and droplets of distilled water. Film thickness measurements were performed through profilometry. Results showed that MA films obtained through the active screen system are thicker and more efficiently preserve the anhydride groups than those obtained from conventional plasma discharge.

The principal cellulose ester fiber is cellulose acetate, a partially acetylated cellulose, also called acetate or secondary acetate. Although widely used in textiles, its primary use is now for the preparation of cigarette filters, which consumed 65% of the 731,000 metric tons produced worldwide in 1991. Cellulose triacetate is an almost totally acetylated cellulose, but environmental considerations encountered in the preparation of fibers have almost totally eliminated its production. This article initially describes the physical and chemical properties of cellulose acetate and triacetate polymers and fibers. A review of the manufacturing process operations and considerations follows, providing an overview of the key process steps. Since both textile and cigarette filter applications are commercially important, both are described to illustrate the products available and how they are used. Finally, a brief overview of some smaller volume applications provides some insight into other possible uses.
