We used surface treatment technology to handle wasted polyurethane foam in this paper. And made out a series of new oil absorbed foams to realize the waste reused. We used the following two technical schemes to improve oil absorption of the polyurethane foam: {circled digit one} Dealing polyurethane foam with tung oil;{circled digit two} Dealing polyurethane foam with tung oil and organic silicon compoundly. Study shows the oil absorbency is up to 22.4 times when using tung oil, at the same time when the concentration of organic silicon is 1:5, the oil absorbency is 16 times. The oil absorption effect of polyurethane soft foam which experiences the twenty-minute tung oil processing is the best. © (2014) Trans Tech Publications, Switzerland. Source

Taking zirconium glyphosate (ZrGP) as raw material and a mixture of glycol and ethanol as support material, this paper described a general process to synthetize a new type of porous material. After pushing open the layers of ZrGP by ethanol, this window-type porous compound was formed by esterification between hydroxyls on both ends of glycol and the carboxyls internal laminated panel of ZrGP accompanying with dehydration. SEM image and XRD patterns proved that the pore size distributions of the modified assembly centered at about 55 nm, which was classified as macroporous. Since the formed pore walls were builted up by inorganic skeleton and organic chain, the specific surface area of the sample was determined to 260 m 2 • g -1. In addition, the new macroporous material will have a great prospect in adsorption and catalysis due to the existence of coordinative groups in pores. Source
