synthesis of poly(styrene-co-butyl acrylate)/clay nanocomposite via in situ aget atrp

Use of alcohols as reducing agents for synthesis of well-defined polymers by AGET-ATRP.

Alcohols have been demonstrated to be efficient reducing agents for AGET-ATRP for the first time. Well-controlled polymerizations have been successfully achieved with the typical characteristics of "living"/controlled radical polymerization.

Microencapsulation of Butyl Palmitate in Polystyrene-co-Methyl Methacrylate Shell for Thermal Energy Storage Application

MicroEncapsulated Phase Change Materials (MEPCM) are green materials which could be used for thermal energy saving applications in buildings as a non-pollutant method for environmental. PCMs could passively reduce peak cooling loads in hot seasons because of their high energy storage capacities at a constant temperature. Purpose of this paper is manufacturing Microencapsulated PCM (MPCM) pr...

Synthesis of Silica/Polystyrene Nanocomposite Particles by Miniemulsion Polymerization

Miniemulsion polymerization is one of heterogeneous polymerization method that can be effectively used to synthesis of various novel organic-inorganic nanocomposite particles. This method can provide opportunity of good incorporation between the polymer and inorganic phases in the formed submicrometer-sized particles. In this article, we report preparation polystyrene/silica nanocomposite p...

Synthesis of Poly(n-butyl acrylate) Homopolymers by Activators Generated by Electron Transfer (AGET) ATRP Using FeCl3·6H2O/Succinic Acid Catalyst

سنتز نانوکامپوزیت‌های پلی‌استیرن/‌MCM–41 به روش‌های AGET ATRP و ARGET ATRP

نانوکامپوزیت‌های پلی‌استیرن/MCM–41 به روش پلیمرشدن رادیکالی انتقال اتم (ATRP) در دمای 110 درجه سلسیوس سنتز شدند. روش‌های آغاز فعال‌کننده‌هایی که با انتقال الکترون تولید می‌شوند (AGET) و فعال‌کننده‌هایی که با انتقال الکترون بازتولید می‌شوند (ARGET) به­ عنوان دو روش نوین آغاز در ATRP به­ کار گرفته شدند. ساختار ویژه، مساحت سطح، اندازه ذرات و توزیع آنها و ساختار اسفنجی و حفره‌ای نانوذرات MCM–41 سنت...

Fabrication of Ti3SiC‌‌2-SiC max phase composites via in-situ and ex-situ synthesis

Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...
