A modified resorcinol resin is prepared by reacting a phenolic compound (e.g., resorcinol) with an olefinically unsaturated compound (e.g., styrene) and two types of aldehyde: a formaldehyde and an alkyl aldehyde (e.g., butyraldehyde). The reaction is typically carried out in the presence ...
The synthesis of templating porous carbons can be dated back to 1980s, when Gilbert et al. [23] reported a work about charring the mixture of phenol-formaldehyde resin and silicone at 1000 °C. Their work provided a new idea for researchers to the synthesis of porous carbons which has dev...

bamboo scrimber product is comprised of Phyllostachys pubescens (Moso) with a phenol formaldehyde resin. The final product is a 140 Â 140 mm section available in varying lengths. As shown in Fig. 2 and discussed in the previous section, the pro- ...
The precursor is impregnated with a phenol-formaldehyde or furfural resin or their mixture. The used resin preferably should not graphitize during the later carbonization. Additives, like metallic salts or graphite can be used. This process can be modified by using volatile additives (e.g., ...
Wood-based superhydrophobic surfaces could represent a more environmentally benign material for remediating spills. Na3(Cu2(CO3)3OH)∙4H2O was synthesized in situ on delignified balsa wood reacting copper chloride and sodium hydroxide in the presence of phenol formaldehyde (PF) resin, and then mo...
