Microencapsulation by in situ Polymerization of Amino Resins

Radar absorption of FeNi nanoparticles and FeNi@PANI nanocomposites prepared by in-situ polymerization

In this research, FeNi@PANI nanocomposites as the electromagnetic wave absorbers were prepared through two following steps. At first, FeNi alloy nanoparticles were synthesized by the one-pot polyol process, and then, in-situ polymerization method was used for the preparation of FeNi@PANI nanocomposite. The XRD pattern confirmed the formation of pure FeNi alloy with the FCC crystalline phase. Th...

Preparation and Characterization of Layered Silicate Polyethylene Terephthalate Nanocomposite by in Situ Polymerization

A series of experiments on the synthesis of poly (ethylene terephthalate) (PET)/organo-montmorillonite (MMT) nanocomposites were carried out in a pressurized reactor using alkyl ammonium exchanged smectite clays, (Closite 30B).Given the degradation of organoclay at high temperatures, the in situ polymerization process was carried out at mild temperatures ranging from 210 to 230°C for 40 minutes...

Electrical properties of UHMWPE/graphite nanoplates composites obtained by in-situ polymerization method

There are described nanocomposites based on ultra high molecular weight polyethylene and graphite nanoplates prepared by in-situ polymerization method. It is carried out a comprehensive study of electric properties of these composites, including direct current (dc) and alternating current (ac) properties. There is explored dependence of the conductivity and dielectric permeability on filler con...

Microencapsulation of Ethion by Interfacial Polymerization Utilizing Potassium Phthalimide-N-oxyl (PPINO) as a Promoter

Polymerization shrinkage of dental composite resins.

Aesthetic materials have always been a priority for the restoration of anterior teeth; increasingly, they have also gained prominence in the restoration of posterior teeth. This has been due to their advantages as an alternative to amalgam. Their drawbacks however, can include poor marginal adaptation, postoperative sensitivity and cuspal movement. These are particularly associated with the pol...
