ABSTRACT.Carbon black (CCB)/Hydroxypropyl methylcellulose (HPMC) composites were useful for the sensor applications. Easily available Carbon black was preferred for the modification of polymer moieties. Due to an excellent coloring agent, printing inks, resin coloring, paint, and toners. Further, CCB is also used in various electrical conducting agent, antistatic film, fibers and floppy disk. In the present investigation we demonstrated the successful preparation of Hydroxypropyl methylcellulose with (CCB) composites. We have observed the linear phase relation as a function of temperature for the sample 1wt% loading of CCB. The linearity of phase measurement based on temperature is useful for various engineering applications.
Introduction. Development of electrically conducting organic carbon based polymer composites prepared by fusion of nanofillers such as flakes [1], carbon black [2], graphite [3] have attracted researchers for decades due to their extraordinary properties like high stiffness, low weight and high electrical conductivity in the range of 10-1-102(ohm cm-1) [4]. CCB are used in various electrical, mechanical and thermal properties [5]. Property of the polymer may change by loading the concentration of filler [6]. Due to these unique properties of carbon we have chosen to prepare polymer composite using CCB as filler. Generally, polymers are non-conducting in nature; to optimize its conductivity was more challenging research interest. They possess low weight, decompose-resistant materials which are used in a wide variety of industrial and military, sensor applications [7]. Hydroxypropyl methylcellulose (HPMC) is a different grade cellulose polymeric family, a natural carbohydrate that holds continuous glucose structural units. It is hydrophilic polymer with wide useful properties like fluid retention purpose, lubricants, natural gum and emulsifiers, used as thickener, film former, and excellent drug delivery component in oral medication [8]. Inflexible hybrid composite film using Carbon black/rubber have been prepared and used in engineering applications [9], But there may some technical difficulty in casting composite with rubber. Using Carbon black with PET and PMMA a composite was prepared and their surface investigations were studied [10], polymer used in particular work is highly costly. In our present study we prepared polymer composites using HPMC/CCB and disclosed their phase angle response. Where HPMC is cheaper material and easy to casting the film.
