Abstract Scope |
While the porous materials are studied for various applications, their thermal behaviour is scantly reported. Addressing this, constructs with varying porosity were fabricated using Pickering emulsion templating. Stable emulsions of ε-caprolactone (CL) were prepared using silica nanoparticles as stabilizers and silicone oil as dispersed phase, which were further in-situ polymerized to form 3D nanocomposite constructs. The extent of porosity was controlled by dispersed phase volume of emulsions and crystallization behaviour was investigated under non-isothermal conditions. It was observed that inclusion of porosity led to extremely diminished crystallization temperature and kinetics. Various crystallization models were utilized to explain their crystallization behaviour. While a 3-regime crystallization was demonstrated by nonporous construct, presence of porosity led to 2-regime crystallization behaviour. This change in crystallization kinetics of the material was further prominent in materials with higher extent of porosity (>70%). Additionally, significant changes in crystalline structure due to porosity observed in x-ray diffractometer. |
