Abstract The polymer/wood functional products may not be true nanocomposites due to the poor permeability of non-polar monomers into hydrophilic wood cell wall. In this paper, methyl methacrylate (MMA) chosen as representative monomer was used impregnate with different lignin removal and then polymerized in situ delignified obtain polymethyl methacrylate/delignified (PMMA/DW). larger 10 nm meso...
Patterning of Polymers on a Substrate via Ink-Jet Printing of a Coordination Polymerization Catalyst
The generation of laterally structured patterns of conju gated, conductive polymers on flat substrates is a key step in the development of new technologies for the production of, for example, displays or low cost flexible circuits. Printing and related procedures, in which the pattern of the individual pieces produced can also differ from one another, are patterning techniques suited for mass p...

Preeious metal alloys bondcd by the adhesive r'esin were thermocycled O, 1,OOO, 2,OOO, or 4,OOO times in water between 4 and 60°C , and tensile bend strengths were measurecl. Debonded metal surfaces after the tensile test were analyzed based on an area of cohcsive failure. Three-way ANOVA revealed that all the three parameters adherend, adhesive rnonemer, and nurnber of thermal cycles exhibited...
methyl methacrylate (mma), a widely used monomer in dentistry and medicine has been reported to cause abnormalities or lesions in several organs. experimental and clinical studies have documented that monomers may cause a wide range of adverse health effects such as irritation to skin, eyes, and mucous membranes, allergic dermatitis, stomatitis, asthma, neuropathy, disturbances of the central n...
A model was developed to aid in the selection of healing monomers that can rapidly dissolve catalysts in self-healing materials. Predictions are made regarding dissolution rates of Grubbs’ catalyst in a small library of ring-opening metathesis polymerization (ROMP)-active norbornenyl-based healing monomers. The Grubbs’ catalyst and the healing monomers were experimentally assigned sets of Hanse...
In many real world problems, data sometimes comes from n agents (n≥2), multipolar information exists. For issues that are associated with uncertainty, this information can not be showed with the values of crisp, fuzzy, intuitionistic or bipolar. Graph is one of the mathematical models widely used in different sciences. Ambiguity in a graph where data depends on the n parameter can not be showed...
