Preparation and Properties of Melamine Urea-Formaldehyde Microcapsules for Self-Healing of Cementitious Materials
Self-healing microcapsules were synthesized by in situ polymerization with a melamine urea-formaldehyde resin shell and an epoxy resin adhesive. The effects of the key factors, i.e., core-wall ratio, reaction temperature, pH and stirring rate, were investigated by characterizing microcapsule morphology, shell thickness, particle size distribution, mechanical properties and chemical nature. Micr...
متن کاملPreparation and Characterization of Poly (urea- Formaldehyde) Walled Dicyclopentadiene Microcapsules
Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...
متن کاملUrea-phenol-formaldehyde microcapsules containing linseed oil for self-healing anticorrosive coating applications
Novel self-repairing Urea-Phenol-Formaldehyde (UPF) microcapsules containing linseed oil were prepared via in-situ polymerization in an oil-in-water emulsion. The main purpose of encapsulation is to control the release of linseed oil, when external conditions such as mechanical stress or energy cause microcapsules to break. These controlled release mechanisms of linseed oil make them suitable f...
متن کاملInvestigation of self-healing in cementitious materials with sulfoaluminate cement microcapsules using X-ray computed tomography
This paper presents work toward the studying of a new family of self-healing cementitious material. This innovative system features the design of microcapsules with calcium sulfoaluminate cement (CSA) as healing agent. The aim of this study is to comprehensively monitor the whole crack-healing process of microcapsules based self-healing system by means of X-ray computed tomography (X-ray CT). I...
متن کاملExperimental Study on Mechanical Properties and Porosity of Organic Microcapsules Based Self-Healing Cementitious Composite
Encapsulation of healing agents embedded in a material matrix has become one of the major approaches for achieving self-healing function in cementitious materials in recent years. A novel type of microcapsules based self-healing cementitious composite was developed in Guangdong Provincial Key Laboratory of Durability for Marine Civil Engineering, Shenzhen University. In this study, both macro p...
