The effect of a small amount of chemically reduced graphene oxide (CRGO) on the isothermal and nonisothermal phase separation behavior of poly(methyl methacrylate)/poly(styrene-co-acrylonitrile) (PMMA/ SAN) blends was investigated by using time-resolved small angle laser light scattering (SALLS). During the non-isothermal process, a quantitative logarithm function can be established to describe the relationship between the cloud point T c and heating rate k as given by T c ¼ A ln k + T 0 for the unfilled and filled CRGO-filled PMMA/SAN systems. During the isothermal process, the TTS principle and WLF function are applicable to describe the temperature dependence of nonlinear phase separation behaviors at the early and late stages of spinodal decomposition (SD) for such unfilled and filled systems, indicating that the introduction of CRGO hardly changes the viscous diffusion essence of macromolecular chains during phase separation. However, the mechanical barrier effect of CRGO on the macromolecular viscous diffusion may result in the delay of their phase separation behavior. Furthermore, the effect of CRGO on the isothermal and non-isothermal phase-separation behavior of the blend matrix is found to be dependent on the composition of the blend matrix. CRGO may act as a nucleating agent to result in the decrease of T c for the PMMA/SAN 37/63 system, while the mechanical barrier effect of CRGO on the macromolecular segment may retard the concentration fluctuation at the early stage of SD phase separation to cause the increase of T c for the PMMA/SAN 57/43 system. Besides, when SAN is the minority of the blend matrix (PMMA/SAN 57/43), the selective location of CRGO may result in the more obvious viscosity increment and then the more remarkable hindering effect on the SD phase separation behavior of blend matrix.

“…Summarizing, one can state that particle and nanoparticle reinforcements allow drastic increase of the erosion resistance of polymer coatings. Still, the usefulness of nanomodification strongly depends on the used technology (functionalization, nanoreinforcement), distribution and exfoliation of nanoparticles, their shapes, and quality …”

Factors and structural parameters of coatings influencing the efficiency of protective coating systems against rain erosion of wind turbine blades are reviewed. The possibilities to enhance the attenuation of wave energy from droplet impact, increase damping and varying stiffness, creating interfaces for wave reflection, adding reinforcement for wave scattering, and creating additional layers or skeleton‐like reinforcing or wave absorbing structures, are discussed in the paper. Formulas for quantitative estimation of these effects as well as qualitative relationships between the structural parameters of coatings and their performance are presented. Recommendations and promising directions for the improvement of the protective coating systems for rain erosion protection of wind turbine blades are presented.

Keywords-Acrylonitric Butadiene Styrene (ABS), Fusion Deposition Modelling (FDM), Computer Aided Design (CAD, 3D (Three Dimensional), Carbon Nano Tubes (CNTs), GO (Graphene Oxide), Molecular Dynamics (MD)When designing a new product, engineers can best predict its end performance by prototyping with a material as similar to it as possible. A part produced has to deliver its performance in actual prevailing conditions. When designing a product, knowledge of material properties is very essential so that it can be judged whether the material can serve the intended purpose (and upto what extent) or not. Thus properties of material affect its performance and knowledge of actual performance environment helps in selection of material and its material properties. Depending on the end use, material properties are decided by the designer. Thus processing of materials is also a crucial area of study. The aim of the present work is to make a step in prediction of prototype performance of part and its material properties, thus present a road map accordingly.Processing of biomedical parts consisting of various biocompatiple properties is emerging area of study in material science. There are many processed materials which are used for biomedical applications depending on their properties. Some of the biocompatible thermoplastic materials are acrylonitric butadiene styrene (ABS), PC-ISO etc. Medical, pharmaceutical and food handling equipment have stringent regulations to protect consumers from illness and disease. Regulations include standards such as ISO 10993 and USP Class VI, which classify a material as biocompatible. ABSM30i meets these criteria so it can be used for products that come in contact with skin and food.ABS-M30i blends strength with sterilization capability. ABS-M30i can be sterilized using either gamma radiation or ethylene oxide (Eta) sterilization methods.
