- Surface analysis and water contact angle of modified natural biopolymers - ScienceDirect
Operating nanocellulose for film reinforcing to assure improved characteristics is highly important Owing to their high hydrophilic property, pure macroalgae films exhibited a water contact angle (WCA) of 41 27 degrees and an approximate roughness value of 49 2
- Hydrophilicity and Water Contact Angle on Methylammonium Lead Iodide - Caddeo - 2019 - Wiley Online Library
Present work reconciles the hydrophilic nature of methylammonium lead iodide with the apparent hydrophobic behavior in contact angle measurements, proposing a methodology for the study of contact angle on evolving substrates
- Use of Flory Huggins Interaction Parameter and Contact Angle Values to Predict the Suitability of the Drug-Polymer System for the . . . - Springer
All three polymers provided lower equilibrium contact angle values when compared to purified water, indicating an afinity for polymers Successful production and stability of several nanosuspensions were correlated with Flory–Huggins’s interac-tion parameter and contact angle values
- Surface-wetting characterization using contact-angle measurements
Low contact-angle values demonstrate a tendency of the water to spread and adhere to the surface, whereas high contact-angle values show the surface’s tendency to repel water The
- Exploring Water Contact Angle and Its Implications
High surface energy materials, like metals, tend to be more 'wettable,' meaning water spreads more on their surface, leading to lower contact angles On the flip side, materials with low surface energy, for example, certain plastics or waxy substances, repel water, resulting in higher contact angles
- Water Contact Angle - an overview | ScienceDirect Topics
Conventionally, surfaces exhibiting a water contact angle higher than 90 are considered hydrophobic, and surfaces exhibiting a water contact angle lower than 90 are considered hydrophilic Contact angle is a very crucial parameter defining the degree of wettability of a membrane surface, which mainly depends on the chemistry of the polymer and
- Contact Angles and Wettability: Towards Common and Accurate Terminology - ResearchGate
In this contribution, key terms used in relation to contact angles are defined precisely based on the accumulative knowledge from the surface chemistry community over the last decades The
- Hydrophobin-enhanced stability, dispersions and release of curcumin nanoparticles in water - PubMed
The rHGFI-Cur nanocomposites were characterized by contact angle, transmission electron microscopy, fluorescence microscopy and dynamic light scattering The results showed that rHGFI could lead to the wettability conversion and stability improved of Cur in water
- Improving the Dissolution Rate of Poorly Water Soluble Drug by Solid Dispersion and Solid Solution—Pros and Cons - Taylor Francis Online
In solid dispersion, P188 improved the wetting of the drug, increased the intrinsic solubility, and thus improved intrinsic dissolution rate of the drug The contact angle studies were well correlated to the dissolution studies for the physical mixture and solid dispersion
- Direct determination of three-phase contact line properties on nearly molecular scale
Here we report the first direct experimental determination of contact angles as well as contact line curvature on a scale of the order of 1nm For water nucleating heterogeneously on Ag
