Preparation and Characterization of Novel Microcapsules

Preparation and Properties of Olive Oil Microcapsules

In this paper, microcapsules were produced by complex coacervation using gelatin and acacia as wall materials and olive oil as the core substance. Process parameters, such as the dosage of the crosslinker, concentration of the wall materials, pH Value and the ratio between core and wall materials were analyzed in detail. Moreover, crosslinking degree of wall materials was more important in obta...

Research of Amoxicillin Microcapsules Preparation Playing Micro-Jetting Technology

With polylactic-co-glycolic acid(PLGA) as shell material of microcapsule, amoxicillin as the model, poly(vinyl alcohol) and twain as surfactant, amoxicillin-PLGA microcapsules were manufactured using digital micro-jetting technology and a glass nozzle of 40μm diameter. The influences of the parameters of micro-jetting system on the mean grain size and size distribution of amoxicillin-PLGA micro...

Preparation 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...

A Rapid and Efficient Route to Preparation of Isocyanate Microcapsules

In this paper, polyaryl polymethylene isocyanates (PAPI) were used as an innovative alternative material to prepare isocyanate microcapsules. PAPI could be used as core materials, which would react with small molecules containing active hydrogen (1,4-butanediol, ethylene glycol, 1,2-diaminoethane etc.). The reaction products of PAPI and active hydrogen would form a shell by interfacial polymeri...
