Porous structure of polybenzoxazine-based organic aerogel prepared by sol–gel process and their carbon aerogels

Recycling of carbon fibre reinforced polymeric waste for the production of activated carbon fibres

“…The second peak, appeared at 500 • C once the air was introduced and represents the combustion of the char. Lorjai et al [13] used thermogravimetric analysis to investigate the thermal degradation of polybenzoxazine. They pointed out that polybenzoxazine began to lose weight at 250 • C, and the highest maximum mass loss rate was observed in the temperature range of 250-600 • C. Hung et al [14] studied the thermal degradation of pure phenolic resin by TGA from room temperature to 800 • C with a heating rate of 10 • C min −1 under nitrogen atmosphere.…”

Development of Poly(d,l-Lactic Acid) With Polybenzoxazine via Solution Blending

“…The polybenzoxazine precursors were prepared by mixing bisphenol-A, TETA, and formaldehyde at a mole ratio of 1:1:4, respectively [6,7]. Firstly, bisphenol-A (6.84 g, 30 mmol) was dissolved in 1,4-dioxane (15 mL) in a 50 mL glass bottle and was stirred until a clear solution was obtained.…”

Advanced and economical ambient drying method for controlled mesopore polybenzoxazine-based carbon xerogels: Effects of non-ionic and cationic surfactant on porous structure

“…In addition, polybenzoxazine is a cross-linked polymer with additional extensive hydrogen bonded networks which can withstand pore collapse without the need of supercritical CO 2 drying process. Hence, polybenzoxazine aerogels with more economical ambient drying have been reported in the literature [35][36][37][38][39][40][41][42].…”

“…In 2009, polybenzoxazine-based carbon aerogels were first introduced by Lorjai et al who found that their carbon aerogel exhibited the properties as a microporous material [35]. In 2010, polybenzoxazine-based carbon aerogels with an average pore diameter of 3.67 nm were used as an electrode in supercapacitors by Katanyoota et al [36].…”
