Chemical affinity and dispersibility of boron nitride nanotubes
this work, the chemical anity of puried BNNTs, measured in terms of Hansen solubility parameters (HSP), were obtained through sedimentation tests in a wide set of organic solvents, taking into account relative sedimentation time. The parameters obtained were {d d; d p; d h} {16.8; 10.7; 14.7} {0.3; 0.9;
Hansen solubility parameters of cellulose acetate butyrate
The specific retention volumes, $$ V_{\text{g}}^{0} $$ , for adsorption of 21 solute probes on the solid surface of cellulose acetate butyrate (CAB)–poly(caprolactone) diol (PCLD) blend determined in the temperature range by inverse gas chromatography were used to evaluate Hansen solubility parameters (HSP). The effect of plasticizer, PCLD, on the HSP of CAB was investigated. The three

Polymer additives and solubility parameters - ScienceDirect
1. Background. Additives used in polymers can be characterized by Hansen solubility parameters (HSP), just like polymers. These usually have the symbols δD, δP, and δH, which are sometimes replaced by D, P, and H, for convenience. The assignment of HSP to both additives and the polymers to which they are added allows predictions of behavior
- What are Hansen solubility parameters (HSP)?
- The solid and liquid additives used in polymers can be characterized by Hansen solubility parameters (HSP). Compatibility is found when these parameters for the polymer and the additive are close enough to each other. Mismatches lead to phase separation, or in the case of solid surfaces, to poorer adhesion than that otherwise attainable.
- What are Hildebrand and Hansen solubility parameter models?
- In this study, we focus on two well-established models, namely, the Hildebrand and Hansen solubility parameter models. Both models are built on the basis of the notion of “like dissolves like” and identify a liquid as a good solvent for a polymer if the solubility parameters of the liquid and the polymer are close to each other.
- What are Hansen Solubility Parameters in polymer additives?
- Polymer additives can be assigned Hansen solubility parameters (HSP). Potential predictions of the physical behavior of polymeric additives in polymers are therefore possible. This allows systematic studies of compatibility, surface affinities, and the like to improve the performance of the coatings and plastics containing these additives.
- What are Hansen three-dimensional solubility parameters?
- The Hansen three-dimensional solubility parameters (HSP) were used to obtaining the solubility parameters of five of the most used polymer materials from swelling tests with forty chemicals covering a broad spectrum of HSP values.
- What is Hansen solubility approach?
- The Hansen solubility approach states that for chemicals where the solubility parameter distance (A) of a given chemical to the center of the polymer sphere is higher than the R value, A/R >1, the material will be resistant and inversely, for A/R < 1 the material will be not resistant.
- What is Hansen representation of the polymer solubility sphere?
- Figure 1. Hansen representation of the polymer solubility sphere are outside the sphere. Hansen formalized the concept of RED considered to be not resistant to the solvent. Efforts has been chemical resistance of pro tective material (Hansen, 1988). others (r=0.9). Perkin s et al. (1985) analyzed the use of HSP protective materials candida tes.
