	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 = {Polyurea microcapsules containing water-soluble reactive polyamine, namely, polyaziridine (A33), were prepared by interfacial polymerization technique in non-aqueous medium, wherein (i) A33 was encapsulated for the first time as a neat amine without forming its salt or adduct and (ii) microcapsules formed were without any deleterious effect on A33. A systematic study was conducted by preparing microcapsules with different polyurea wall architectures. Fourier transform infrared (FTIR) and proton nuclear magnetic resonance (H-1 NMR) spectroscopic analysis of extracted A33 from microcapsules do not show any structural changes during microencapsulation. A titration method was developed to analyze the amount of encapsulated A33 quantitatively. Polyurea microcapsules obtained from reaction of ethylene diamine (E) and isophorone diisocyanate (I) monomers have shown better properties such as encapsulation efficiency and extent of agglomeration. Significant reduction in the size was observed when microcapsules of EI wall material were prepared by homogenizing the initial emulsion of A33 in paraffin oil. The process described in this paper for the preparation of microcapsules is cost-effective and industrially viable, which can find applications in agrochemicals, coatings, self-healing composites, etc.},

	abstract = {Nanocomposites of epoxy resin and clay modified with half neutralized salt of Jeffamine D400 were prepared by curing separately with three polyetheramines curing agents of different molecular weights and reactivity. The molecular weight of curing agents and their structural similarity with modifier played an important role in deciding the curing behavior, thermomechanical, and morphological properties of epoxy/clay nanocomposites. Morphological analysis carried out by X-ray diffraction (XRD) and transmission electron microscope (TEM) clearly show that the dispersion of clay layers in epoxy matrix decreases with decreasing molecular weight of the curing agents. Curing study done by using temperature modulated differential scanning calorimetry (MDSC) demonstrates that extragallery reaction rate increases with decreasing molecular weight of curing agents. Dynamic mechanical analysis (DMA) of epoxy/3 wt \% modified clay composite prepared by curing with curing agent of higher molecular weight shows around 270\% improvement in storage modulus (glassy) as compared with its neat epoxy network.},

	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.},
