Studies from University of British Columbia Update Current Data on Cellulose Research (Ultra-lightweight paper foams: processing and properties)

July 1, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Life Science Research are presented in a new report. According to news reporting originating from Vancouver, Canada, by NewsRx correspondents, research stated, "A methodology for producing a low density cellulose-based foam has been developed by combining a surfactant with pulp, mixing at high velocity to entrain air, and then drying in a non-restrained fashion. The structure of the foam, characterized through optical microscopy and X-ray computed tomographic microscopy, consists of pulp fibres in random orientations surrounding air bubbles along with large void spaces."

Our news editors obtained a quote from the research from the University of British Columbia, "Through careful design of experiments, the effect of fibre type, length distribution, surfactant, and air content on the mechanical behavior and permeability of the foam material was investigated. The results indicate that foamed cellulose materials can be produced at a strength of one-half the tensile strength of a standard handsheet, but having a relative density of only one percent. No chemical additives were used to enhance the strength of these samples as the properties of the foam material are enhanced simply through variation of the process parameters."

According to the news editors, the research concluded: "Thus, a strong cellulose-based foam, with a density as low as 10 mg/cm(3), can be fabricated using standard papermaking infrastructure and hence at low cost."
