Description
Technical field
This patent announces a kind of proving installation of 3D contact angle.This device is made up of sample platform system that is vertical and that horizontally rotate, adopt the precision optics rotation platform of worm gear structure to control camera lens, video camera to rotate along Vertical dimension together with sample stage, adopt the horizontally 360 degree of rotations of optics rotation platform Quality control platform.This device and method of testing can the hysteresis quality contact angle values that cause such as analysis of material chemical diversity, isomery, anisotropy and rough surface, have extremely wide promotional value in fields such as the researchs such as new material, biomimetic material.
Background technology
Liquid-liquid interface tension force, liquid-basic index such as gas meter surface tension and solid-liquid contact angle values is the basic parameter characterizing material physicochemical property.Contact angle refer in solid level plane drip on a droplet drop, the solid-liquid on solid surface-gas three-phase point of interface place, the angle (as Fig. 1) formed when its gas-liquid interface and solid-liquid interface two tangent line are clipped in liquid phase wherein.Contact angle values be one by a material inherently index comprehensively determining of the various factors such as character, chemical isomerization, surface physics structure, surface clearness.Due to reasons such as materials chemistry anisotropy and rough surface, often cause contact angle to be formed at material surface delayed, be presented as that left and right contact angle values is inconsistent or completely different, form non-axis symmetry drop.
In actual measuring technology, method conventional is at present the dynamic Contact angle value that test comprises advancing angle, receding angle and roll angle.In the test process of dynamic contact angle, this is tilted by solid sample to commonly use a kind of method, test is affected by gravity the dynamic Contact angle value under condition when tilting, and the mechanism completing this class testing is mainly divided into two classes: one, adopt sample stage vertical rotation, the mode that camera lens (being connected with camera) does not rotate; This method requires that institute drips must remain on the center of rotation axis, otherwise drop is easy to movement, and in software algorithm, must complete calculating by coordinate conversion, and software is longer for computing time; They are two years old, adopt the mode rotated by whole instrument, this mode has embodiment in current main flow commercial instrument, its shortcoming clearly, be common belt or gear shift owing to adopting a physical construction, not high, the radial shaking volume of control accuracy of physical construction is very large, is unfavorable for very much dynamic contact angle measured value in rolling situation; Weight simultaneously due to complete machine is very large, controls very inconvenient.
But test dynamic Contact angle value far from can meet practical application, can not characterize contact angle hysteresis and can not characterize the features such as the anisotropy of contact angle in other words.Such as, we record the materials such as Rice Leaf, the leaf of bamboo, silicon chip, have all embodied the difference of the contact angle values of contact angle values under different imaged viewing angle condition and the difference of left and right contact angle values.So test 3D contact angle values just can better the physicochemical property of exosyndrome material.
At present, contact angle and interfacial tension testing tool are all instruments of standard design usually.As " measuring analyzer for dynamic characteristics of liquid surface and interface based on high rate burst communication " patent No. in existing Patent data storehouse: 200610050811.8 and 200620103753.6, " a kind of automatic testing method of static contact angle " patent No. 201010288857.X, " contact angle and surface energy measurement mechanism " patent No.: 201010600278.4, " measuring contact angle device " patent No.: 200710142656.7, " a kind of On-line Measuring Method of self clean glass contact angle " patent No.: 200710008521.1 etc.
The Chinese patent ZL200910034768.X device of synchro measure drop temperature, surface tension, contact angle " a kind of temperature control wet " and ZL201210127093.5 " measuring the device of liquid-drop contact angle and roll angle under wet, the pressure control condition of a kind of temperature control, control ", describe that a kind of temperature control, control are wet, measure the device of liquid-drop contact angle and roll angle under pressure control condition, that a kind of fuzzyyer theoretical property describes, concrete implementation detail is also that generality describes, from enforcement, operability is not strong.
