Introduction Polypropylene (PP) is one of the most widely used thermoplastic in many demanding applications. It has many advantages as a base matrix for thermoplastics composites owing to its relatively low cost and high

structure. Organic materials can be inserted into the layers of stratified silicate to prepare composite material. The stratified silicate acts as a supporting material. It improves the thermal stability and shaping stability [ 8 , 9 ]. Moreover, the

combination of properties. Over the past several decades, blending of liquid crystalline polymer (LCP) with commodity polymers resulting in the so-called in situ microfibrillar-reinforced composite [ 1 , 2 ] has been known to exhibit excellent mechanical

flammable property limits its applications, so it is necessary to prepare these plastic composites with good flame retardant properties. In order to achieve above aim, many methods for improving fire retardancy of LDPE are investigated, and one of the most

Abstract  

Plaster composites have been developed by the authors, aiming the manufacture of plasterboards and other building materials with enhanced properties. Polymeric plaster composites,obtained from hydration of commercial plaster of Paris with aqueous solutions of a commercial polyester, were characterized by thermogravimetry (TG) and differential thermal analysis (DTA). A method using derivative thermogravimetry (DTG) was developed to determine the polymer content in the composites and its distribution. Samples prepared conventionally by hydration of plaster of Paris with water were used as reference. Independently of the initial solution concentration, all the composites show an even distribution of the polymer, which presence enhances the composite mechanical strength.

wastewater. The adsorption process is primarily focused on the use of activated carbon as adsorbent, due to large surface area and predominant proportion of mesopores [ 8 ]. Nowadays, composite materials specially, nanomaterials are considered as alternatives

Introduction In the recent years, an increased interest in obtaining composite materials with natural component as wood sawdust, flax, sisal, jute, and hemp fiber has been observed [ 1 – 7 ]. Lignocellulosics are favored as new

extrapolate the results from one to another CNT/epoxy composite. As it was expected, the results obtained are highly dependent on the nanofiller type (length, number of walls, functionalization, etc.) [ 1 , 2 ]. But, even for the same CNT, their effect

filler addition. In composite systems of semicrystalline thermoplastic matrices, a highly oriented crystalline domain, known as the transcrystalline layer, can be developed around the fibers due to the high density of active nuclei on the matrix
