Hybrid waterborne dispersions provide improved performance in established applications and allow targeting new applications that are out of reach of the conventional homogeneous latexes. They are product‐by‐process materials that are produced by either emulsion or miniemulsion polymerization and whose characteristics are determined in the reactor. Therefore, it is crucial to produce them by means of an optimal process strategy. This work reviews the fundamental knowledge available as well as the missing parts needed to develop such strategy focusing on particle morphology, which is the most distinctive feature of these materials.

“…The room temperature curable polymer is one of the most preferably used adhesives that offer the superior interfacial bonding strength in hybrid structures such as fiber metal laminates . Due to the excellent peel resistance and impact strength, these adhesive layers can be applied to structures such as in automobiles and wind turbines (e.g., to join composite blades to metal hubs).…”

Determining the constitutive model of adhesives enables the prediction of the mechanical response of hybrid structures in which the adhesive is used. In this study, the stress-strain behavior of a two-component structural adhesive was first measured in uniaxial compression experiments at the strain rates ranging from 0.001 to 2600 s −1 for developing a constitutive model. It was found that the compressive response, including elastic modulus, yield strength, and plastic flow stress, is substantially influenced by the strain rate. In plastic deformation, the strain rate sensitivity is not constant but varies with the rate; moreover, strain softening and hardening dominate the plastic deformation at low and high strains, respectively. A visco-elasto-plastic constitutive model was then proposed for the adhesive, integrating the strain rate sensitivity that was quantified by empirical equations. The model which was validated can reliably represent the strain rate dependent compressive behavior of the adhesive.

“…Blending and hybrid process are two main ways to combine the advantages of WPU and AC. Though having the disadvantage of poor compatibility, physical mixing is simple and economical compared with hybrid process . To the best of our knowledge, research using WPU/AC blends to prepare porous coatings for synthetic leather has been seldom reported.…”

Porous-coated fabrics used for synthetic leather were prepared by mechanical foaming method using blends of waterborne polyurethanes (WPUs) and polyacrylate (AC). The effect of AC on structure and properties of WPU/AC coated fabrics was investigated. Fourier transform infrared spectroscopy and differential scanning calorimetry results indicated that there is hydrogen bonding between WPU and AC and the compatibility of the blend system gets worse after AC/WPU ratio is higher than 30/70. Thermogravimetric analysis demonstrated that the thermal stability of porous coatings is improved with increasing AC. Scanning electron microscopy images showed that porous coatings have semi-open cellular structure with a great number of surface pores and window pores, imparting excellent air permeability and water vapor permeability to coated fabrics. On the basis of morphology analysis, the forming process of cell structure of WPU/AC coated fabrics was proposed. Performance tests showed that the overall performance of coated fabrics is best with AC/WPU ratio ranging from 15/85 to 30/70.
