Microencapsulation of Butyl Stearate as Phase Change Material by Melamine Formaldehyde Shell for Thermal Energy Storage

Butyl stearate as a phase change material was microencapsulated within melamine-formaldehyde resin using emulsion polymerization. Morphology and thermal specification of produced microcapsules were studied by Fourier transform infrared spectroscopy, FT-IR, scanning electron microscopy, SEM, and Differential scanning calorimetry analysis, DSC. FT-IR spectra validated the existence of the butyl s...

Microencapsulation of Phase Change Materials for Thermal Energy Storage in Building Application

This paper presents an investigation on microencapsulation of paraffin as a phase change materials (PCMs) for application in buildings. Encapsulated PCM particles were prepared by suspension-like polymerization technique. The effect of surfactant concentration and mass ratio of PCM to monomer on the final characteristics and performance of the microcapsules were investigated. The distribution o...

Modification of cellulose nanofibrils with luminescent carbon dots.

Films and hydrogels consisting of cellulose nanofibrils (CNF) were modified by covalent EDC/NHS coupling of luminescent, water-dispersible carbon dots (CDs). Quartz crystal microgravimetry with dissipation monitoring (QCM-D) and surface plasmon resonance (SPR) were used to investigate the attachment of CDs on carboxymethylated CNF (CM-CNF). As the first reported use of CD in nanocellulose produ...

Nanocomposites of Poly(lactic Acid) Reinforced with Cellulose Nanofibrils

A chemo-mechanical method was used to prepare cellulose nanofibrils dispersed uniformly in an organic solvent. Poly(ethylene glycol) (PEG 1000) was added to the matrix as a compatibilizer to improve the interfacial interaction between the hydrophobic poly(lactic acid) (PLA) and the hydrophilic cellulose nanofibrils. The composites obtained by solvent casting methods from N,N-Dimethylacetamide (...
