Cellulosic Pulp Fiber as Reinforcement Materials in Seaweed-Based Film

Thermosets as compatibilizers at the isotactic polypropylene film and thermomechanical pulp fiber interphase

The objective of this study was to improve interfacial adhesion properties at the interface of thermomechanical pulp (TMP) fiber and isotactic polypropylene (iPP) using thermoset adhesives such as phenol formaldehyde (PF) and urea formaldehyde (UF). This study also attempted to achieve fiber-to-fiber adhesion using thermoset adhesives before the molten iPP would flow into the fiber web. The fra...

Sulfated Seaweed Polysaccharides as Multifunctional Materials in Drug Delivery Applications.

In the last decades, the discovery of metabolites from marine resources showing biological activity has increased significantly. Among marine resources, seaweed is a valuable source of structurally diverse bioactive compounds. The cell walls of marine algae are rich in sulfated polysaccharides, including carrageenan in red algae, ulvan in green algae and fucoidan in brown algae. Sulfated polysa...

Use of Cellulosic Materials as Dye Adsorbents — A Prospective Study

Cellulose is the most abundant biopolymer of nature, and it is widely used in the syn‐ thesis of new materials as well as in the adsorption of dye. This study reports a litera‐ ture review (articles) and technology review (patents) about publications and product invention, which contain information on the use of cellulose on the adsorption of dyes in the period 2004–2014. For this work, researc...

Enzymatic Hydrolysis of Cellulosic Fiber

Thermal Degradation of Cellulosic Materials

Fortisan, cellulose triacetate, and NOroxidized cellulose were pyrolyzed in a vacuum in the temperature range 1800 to 465 0 C. Cotton cellulose and cellulose t ri acetate were also pyrolyzed in nitrogen at atmospheric pressure. The tar yields were in the decreasing order from: Cotton, Fortisan, cellulose triacetate, and oxidized cellulose. The other volatiles consisted mainly of acetic acid, ca...
