Preparation of polyHIPE nanocomposites: Revealing the influence of experimental parameters with the help of experimental design approach

Abstract

Controlling the morphology and physical properties of poly(high internal phase emulsion)s (polyHIPEs) is critical for the development of well‐defined porosity with improved mechanical properties for industrial applicability. Therefore, in this study, experimental design methodology was used to prepare polystyrene based polyHIPE nanocomposites. A surface modified nanoclay was used to reinforce the chalky and brittle polystyrene, and the effect of nanoclay loading was investigated studiously. Emulsion stability has not been compromised due to the presence of modifier groups on the nanoclay surface. A total of 36 samples were produced according to the experimental design matrix. The relationship between the emulsion preparation conditions and final polyHIPE properties including cavity size, interconnected pore size, compression modulus, specific surface area, average pore volume, skeletal density, and foam density were determined by using a statistical software for a 95% confidence level (α = 0.05). In this way, in addition to deriving the empirical model equations for each property, the mutual and synergistic interactions of experimental parameters were also determined.

Sulfonated polyHIPE/nanoclay composites with hierarchically porous structure for efficient removal of endocrine‐disrupting hormone from aqueous solution

“…p(HIPE) and p(HIPE)/NClay monoliths were synthesized according to the experimental procedure reported in the literature previously (Mert & Mert, 2021). Both monolith AIBN (0.42 mmol) were placed in a two-necked reactor, which is equipped with an overhead stirrer and a peristaltic pump inlet.…”

Hierarchical Macroporous PolyDCPD Composites from Surface-Modified Calcite-Stabilized High Internal Phase Emulsions

“…Accordingly, we prepared macroporous polyDCPD composites from the ring-opening metathesis polymerization (ROMP) of HIPEs, which were stabilized using a combination of surface-modified calcite ( m Calcite) particles and a non-ionic polymeric surfactant. Because common emulsion parameters effect the pore architecture and physical properties of polyHIPEs [ 33 , 34 , 35 ], we performed a systematical study for the synthesis of polyHIPE composites. With this aim, we used an experimental design methodology to propose an experimental route in the design of macroporous polyDCPD/ m Calcite composites for future applications.…”

CuO Nanoparticle@Polystyrene Hierarchical Porous Foam for the Effective Encapsulation of Octadecanol as a Phase Changing Thermal Energy Storage Material

“…To overcome these limitations, in addition to PCM microcapsules, − the application of shape-stable porous materials as a PCM carrier has received great interest in the literature. − To date, porous clay, mineral-based materials, metallic foams, porous carbon, and porous polymers , are the most commonly used framework materials for shape-stabilized PCM. High internal phase emulsion templated polymers (PHP) as porous polymers have been used in a wide variety of applications such as adsorption, , purification, , separation, controlled release, , and scaffolding, and there is limited research in energy storage application. , Recently, porous PHP foams have begun to gain attention for the stabilization of PCMs owing to their superior features such as shape stabilization, enclosure ability, high loading rate, excellent structural stability, and interpenetrating pore morphology. − PHPs are monolithic, controllable, highly porous polymers with low density, high specific surface area, highly cross-linked polymer matrix, the porosity of which is created by the continuous phase of emulsions. PHPs in particular stand out for their large gaps bounded by small windows on the skeleton.…”
