Commercially available silica gel is chemically modified for carbon dioxide capture. Calcinated silica gel of certain particle size functionalized with amine using two different methods, wet impregnation and grafting via silane chemistry has been employed as a porous media. The prepared material is characterized by Fourier transform infrared, scanning electron microscopy, energy dispersive anal...

This mini-review article addresses the development in synthesizing polyolefin/clay nanocomposites by olefin polymerization under catalysis of clay intercalated precatalysts in recent years. The review comprises three parts which focus on mainly the synthetic route, structural characterization, and properties of polyolefin/clay nanocomposites, respectively. Moreover, outlook for future research ...

In this study, anatase titania was utilized to prepare a durable photocatalytic paint with substantially enhanced photoactivity towards NO oxidation. Consequently, alleviate the choking effect of and incorporate self-cleaning properties, parent modified Al(OH)3 number organosilane (tetraethyl orthosilicate, propyltrimethoxysilane, triethoxy(octadecyl)silane, trimethylchlorosilane) coatings. A f...

Ricinoloxazoline maleinate (OXA) was grafted by melt free radical grafting onto polyolefins and elastomers to produce new compatibilizers for polymer blends. Effects of initial monomer and peroxide concentrations on the degree of grafting, on the amount of residual monomer, and on the side reactions were investigated. Reactive compatibilizers could be prepared with a suitable choice of processi...

A method has been developed for the quantitative determination of the composition of thermoplastic wood composites. The method involves area measurements of the two peaks in the derivative curve of a tracing produced by the thermogravimetric analysis (TGA) of a thermoplastic composites sample in an inert atmosphere. This may involve the standard, constant heating rate-method, or the high resolu...

Abstract Filler particle functionalization with thiourethane oligomers has been shown to increase fracture toughness and decrease polymerization stress in dental composites, though the mechanism is poorly understood. The aim of this study was systematically characterize effect type filler surface on physicochemical properties experimental resin composites containing fillers different size volum...

Silylation is an effective means of cellulose modification. However, the condensation reaction process between hydrolysis products silane coupling agent and cellulose, as well structure coating, which both have a strong influence on wettability, are still controversial. In this paper, reactions different methyltriethoxysilane with were simulated via density functional theory method. The activit...

Polyolefin, as one of the most widely used macromolecule materials, has been one of the most serious threats to the environment. Current treatment methods of waste polyolefin including landfill, incineration, and thermal degradation have suffered from severe problems such as secondary pollution and the generation of other toxic substances. In this article, we report for the first time a high-ef...
