From the results of TEM and IR, the polymers were proved not only to improve the agglomeration of the nanoparticles but also to be used as a template to control the formation of the special structure and the needed size of Ca(OH) 2 by changing the concentration of the polymers. The experimental results of TG-DTA indicate that the Ca(OH) 2 can absorb most of the acid gases released during the decomposition of polymers. So this kind of nano- Ca(OH) 2 can be used as a useful additive of environmental friendly plastics.展开更多

文摘Calcium hydroxide with uniform diameters about 50—100 nm was firstly prepared under moderate condition by adding different kinds of hydrosoluble polymers.
