Alizadeh, Mohamad published the artcilepH-Responsive MFPTT microcapsules containing dimethyl sulfoxide: Preparation, characterization and tuning the release behavior of microcapsule contents, HPLC of Formula: 7575-23-7, the main research area is melamine formaldehyde pentaerythritol tetrakis mercaptopropionate microcapsule epoxy coating; corrosion inhibitor.
The new approach to intelligent systems is the use of stimuli-responsive micro/nanocapsules to release active ingredients. This work focuses on the preparation of melamine formaldehyde pentaerythritol tetrakis (3-mercaptopropionate) (MFPTT) microcapsules and represent a versatile platform to encapsulate active agent that release capsule contents under alk. condition. DMSO (DMSO) was selected as a solvent that can dissolve a wide range of chem. compound Exptl. results demonstrated that the properties of the capsule shell play a key role in the release rate. Permeability and release of encapsulated payloads were investigated by Field emission SEM (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and UV-visible spectroscopy (UV-vis). It is found that the morphol. of capsules was affected by changing the pH-sensitive agent content. The particle size of capsules that were synthesized at different conditions were in the range of 800 to 9000 nm with a polydispersity index < 0.4. The chem. structure of capsules was investigated with Fourier-transform IR spectroscopy (FTIR), Elemental anal. (ICP) and Energy-dispersive X-ray (EDX). The shell thickness and core fraction of the microcapsules were characterized by using thermogravimetric anal. (TGA). Addnl., the performance of the release inhibitor from microcapsules in the interface of the coating/substrate characterized by electrochem. impedance spectroscopy (EIS) measurement. Progress in Organic Coatings published new progress about Anticorrosive coating materials. 7575-23-7 belongs to class alcohols-buliding-blocks, name is Pentaerythritol tetra(3-mercaptopropionate), and the molecular formula is C17H28O8S4, HPLC of Formula: 7575-23-7.
