1. 1. Flame retardant treated wood : An investigation into phytic acid and its ability to act as a flame retardant agent

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Mattias Ström; Herman Paulusson; [2023]
   Keywords : Flame-retardant; Phytic acid; Wood;

   Abstract : Flame-retardant coatings have been serving their purpose since the romans ruled Europe. These products have been developed through the years, by mixing and synthetizing solutions, which have resulted in effective, although questionable, products due to their impact on the environment and our health.

3. 2. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Julia Sundmark; [2023]
   Keywords : Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

   Abstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

4. 3. Assessing the effectiveness of siloxane-based flame retardants

   University essay from KTH/Kemiteknik

   Author : Josefin Eklund Wallin; [2022]
   Keywords : Polyhderal oligomeric silsesquioxane; POSS; PVC; TGA DSC; DSC; thermal properties;

   Abstract : Polyedrisk oligomer silsesquioxane (POSS) är molekyler som har en inorganisk ryggrad med organiska grupper fa ̈sta utan på. Själva kåren har en bur liknande form och har en hög termisk stabilitet tack vare kisel (Si) och syre (O) som den består av. READ MORE

5. 4. Shielding effect to the flammable fibres offered by inherently flame retardant fibres

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Jasra Khan; [2019]
   Keywords : Inherently flame retardant fibres; flammable fibres; Flame; Non-woven fabric; knitted fabric;

   Abstract :  Flame retardant chemicals were used to make flammable fibres or fabrics flame retardant. Flame retardants protect the flammable material from fire by delaying or preventing the ignition process. The problem with flame retardants is unreliable durability when applied physically or bonded chemically on the surface of the fibre or fabric. READ MORE

6. 5. Effect of PFOS and HBCD on the lipid profiles of developing rainbow trout (Onchorhynchus mykiss) analyzed with UHPLC/Q-TOF-MS

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Vanja Stefanovic; [2018]
   Keywords : Perfluorooctane sulfonate; hexabromocyclododecane; lipid metabolism; UHPLC Q-TOF-MS;

   Abstract : Perfluorooctane sulfonate (PFOS) is widely used in industrial products and is potentially dangerous to the aquatic environment due to not being broken down whether by chemical or biological means, having a half-life of more than 41 years and disrupting hormones. Hexabromocyclododecane (HBCD) is the third most used brominated flame retardant and is of environmental concern as it bioaccumulates and magnifies in the food chain and is highly toxic to aquatic organisms.
