	abstract = {<p>Polyurea/clay nanocomposite microcapsules containing dimethyl phthalate (DMP) as a model compound were prepared by interfacial polymerization technique. Nanoclays namely, montmorillonite Na+ (MMT) and Laponite were incorporated into microcapsule wall and their effects on morphology, thermal properties and release of DMP from microcapsules were investigated. All microcapsules were characterized using scanning electron microscope (SEM), X-ray diffraction (XRD), transmission electron microscope (TEM), thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR) spectroscopy. The present preparation process results in formation of polyurea/clay nanocomposite microcapsule wall with intercalated clay layered as evidenced by XRD and TEM. Nanocomposite microcapsules have shown significant reduction in release of DMP and change in release mechanism as compared to the pristine microcapsules. Nanocomposite microcapsules show good improvement in the fracture strength as compared to pristine microcapsules. The approach used herein is simple and can be adopted to many other polymeric microcapsule systems prepared by different microencapsulation techniques, requiring reduction in release rate and/or mechanism for several applications like pharmaceuticals, agrochemicals, industrially important chemicals, consumer products, etc. (C) 2015 Elsevier Ltd.

	abstract = {Microcapsules with tunable mechanical properties are highly desirable in pressure sensitive applications. We report here a facile approach to prepare polyurea/multiwall carbon nanotube (MWCNTs) nanocomposite microcapsules (MICs) with enhanced stiffness. A model compound dimethyl phthalate (DMP) was used as core material. MWCNTs were modified with reactive functional groups namely carboxyl (-COOH), amines (-NH2), and isocyanates (-NCO) to ensure a stronger interface between polymer wall and MWCNTs. Functionalization of MWCNTs was corroborated by Fourier transformed infrared spectroscopy (FTIR). Scanning electron microscopy (SEM) was employed to study the surface morphology of MICs. The presence of MWCNTs in the microcapsule wall was confirmed by transmission electron microscopy (TEM). MICs with functionalized MWCNTs show almost 100\% increase in stiffness with respect to pristine capsules. All MICs show 92-97 +/- 1\% encapsulation efficiency. The approach used in this paper can be broadly utilized to tune the mechanical properties of the microcapsules.},
