Abstract
The blends of acrylonitrile butadiene styrene (ABS) polymer and liquid crystalline polymer (LCP) were prepared using a melt-blending technique in presence and absence of different types of nanosilica. The effect ofZn++coated nanosilica on thermal, dynamic mechanical, and morphological properties of ABS/LCP blends was studied. TheZn++coated nanosilica showed a significant effect on the above-mentioned properties of ABS/LCP blends by reacting at the interface between ABS and LCP. A substantial improvement in storage modulus of ABS/LCP blends was observed in presence ofZn++coated nanosilica. Epoxy encapsulated nanosilica was also used as a compatibilizer in this blend system. It is known that the epoxy end group reacts with the LCP reacting groups. But in this case, we cannot find desirable results, may be due to the presence of ABS as the matrix. So Zn-ion-coated nanosilica proved to be better than that epoxy encapsulated nanosilica for the ABS/LCP containing blends. The SEM morphology also corroborates the above-mentioned argument.
Highlights
This paper deals with a polymer, which is in ideal material wherever superlative surface quality, colorfastness, and luster are required
This paper aims to study the effects of compatibilizer additions on the mechanical strength and thermal stability behavior of injection molded acrylonitrile butadiene styrene (ABS) containing liquid crystalline polymer (LCP)
It is observed that the reactivity of the Zn++ coated nanosilica towards the LCP and ABS is more efficient than epoxy encapsulated nanosilica, and a sample containing Zn++ coated nanosilica as a compatibilizer is more stable and have better properties in respect to all other blends in the system
Summary
This paper deals with a polymer, which is in ideal material wherever superlative surface quality, colorfastness, and luster are required. The presence of a high modulus and high strength TLCP as a dispersed phase in an engineering plastic can significantly alter the thermal properties of the blended material. ABS is an engineering plastic that finds extensive applications in the home and business appliances and automobile parts due to its cost effectiveness, good processability, and mechanical properties. Because of its good balance of properties, toughness, strength, and temperature resistance coupled with its ease of moulding and high quality surface finish, ABS has a very wide range of applications. These include domestic appliances, telephone handsets, computer, and other office equipment housings, lawn mower covers, safety helmets, luggage shells, pipes, and fittings. Because of the ability to tailor grades to the property requirements of the application and the availability of electroplatable grades, ABS is often found as an automotive interior and exterior trim component [2, 3]
