Various factors influence the tunneling are simplified considering the axial symmetry of the composite lining structure. The analytical expressions for the seepage field,stress,and displacement in the...
Alkali was used to extract collagen from chrome shavings. Grafting modification of collagen was carried out with acrylic ester as grafting monomers. The structure of the product was characterized usin...
Ce0.8La0.2O1.9-attapulgite (Ce0.8La0.2O1.9-ATP) nanocomposite materials were synthesized by co-precipitation method. The microstructure and phase composition of the as-prepared samples were characteri...
Vinyl polymer (dimethyl diallyl ammonium chloride /acrylic acid/2-hydroxyethyl acrylate/acrylamide) was synthesized via free radical polymerization, and then vinyl polymer/zinc oxide nano composite (P...
Using TiCl4 as the titanium source, urea as the precipitating agent, nano-TiO2/fly ash beads composite materials were prepared by hydrolysis-precipitation method. The materials were characterized by S...
Using muscovite as the carrier, TiCl4 as the source of titanium, urea as the precipitating agent, nano-TiO2/mica photocatalyst (TiO2/M) was prepared by the method of hydrolysis–precipitation. The as -...
Waste newspaper fiber was filled in the collagen cross-linked by glutaraldehyde. The effects of deinking fiber, glycerol dosage, glutaraldehyde dosage on the mechanical properties of composite were in...
Nitrogen doped TiO2/sepiolite composite materials (N-TiO2/sep) with different nitrogen contents were prepared by a sol-gel method and characterized by X-ray diffraction (XRD), scanning electron micros...
Biopolymer/layered silicate composites have shown unique advantages and potentials for the passive targeting of drugs because they can overcome the burst drawbacks of organic carrier, increase the dru...
Chrome-tanned collagen fiber is the major solid waste of leather industry which is difficult to biological degradation and would caused serious pollution to the environment. However, the collagen fibe...
A series of novel granular chitosang-poly(acrylic acid)/attapulgite/sodium humate (CTSg-PAA/APT/SH) composite hydrogels were successfully prepared by one-step free radical graft polymerization and app...
In current study, a series of novel guar gum-graftpoly(sodium acrylate-co-styrene)/attapulgite (GG-g-P(NaAco-St)/APT) superabsorbent nanocomposites were prepared by the simultaneous graft copolymeriza...
New pH-sensitive composite hydrogels were synthesized by free-radical graft copolymerization among sodium alginate (NaAlg), sodium acrylate (NaA), and medical stone (MS). Fourier transform infrared sp...
A polyurethane/clay (PU/clay) composite was synthesized. The microstructure of the composite was examined by scanning electron microscopy. The impact properties of the composite were characterized by ...
In this study, a series of pH- and saline-responsive composite hydrogels were prepared by a facile freeradical graft copolymerization amongst hydroxyethyl cellulose (HEC), sodium acrylate (NaA) and me...
