粉体接触角测量仪

什么是接触角测量仪？

接触角是指在气、液、固三相交点处所作的气-液界面的切线与固-液交界线之间的夹角θ，是润湿程度的量度。

Contact angle measurement on xerogel sensitive layer for optical fibre sensor

This paper deals with approach for the detection of chemical vapours based on refractive-index changes of a silica xerogel layer deposited as an optical cladding on the fibre core.

Characterization of polyethersulfone-polyimide hollow fiber membranes by atomic force microscopy and contact angle goniometery

Asymmetric blend polyethersulfone-polyimide(PES-PI)hollw fiber membranes prepared at different air gap and used for gas separation are characterized by atomic force microscopy and by measuring the contact angle of out side surface.

A novel contact angle measurement technique by analysis of capillary rise profile around a cylinder

A new experimental technique and its computational scheme to determine the contact angles of capillary rise profiles around a cylinder are presented.In the experiment,a carefully coated conic glass cylinder was inserted vertically and slowly into a tested liquid.
