Optical contact angle measuring instrumentApplication Scenario:

　　Optical contact angle measuring instrumentPlays a key role in materials science, industrial manufacturing, biomedical and other fields, with typical applications including:

Evaluation of Material Surface Modification

Development of superhydrophobic coatings: Evaluating coating uniformity by measuring contact angle hysteresis (θ A - θ R). For example, when preparing lotus leaf effect coatings on metal surfaces, it is necessary to ensure that θ>150 ° and rolling angle<10 °.

Semiconductor cleanliness testing: Measure the contact angle of deionized water on the wafer surface, where θ<10 ° indicates no organic contamination on the surface and meets SEMI standards.

Performance optimization of industrial products

Paint adhesion prediction: Coatings with a contact angle<30 ° will spread more evenly on the substrate, increasing adhesion by more than 30%.

Hydrophilic modification of textile fibers: By plasma treatment, the contact angle of polyester fibers is reduced from 120 ° to 20 °, significantly improving moisture absorption.

Biomedical materials research and development

Biocompatibility of artificial joints: Measuring the contact angle between polyethylene joint surface and physiological saline, where θ<60 ° can reduce protein adsorption and lower the risk of inflammation.

Drug controlled release carrier design: By regulating the surface wettability of microspheres through contact angle, precise control of drug release rate can be achieved.
