Functional lignocellulosic materials prepared by ATRP from a wood scaffold
Wood, a natural and abundant source of organic polymers, has been used as a scaffold to develop novel wood-polymer hybrid materials. Through a two-step surface-initiated Atom Transfer Radical Polymerization (ATRP), the porous wood structure can be effectively modified with polymer chains of various nature. In the present study, polystyrene and poly(N-isopropylacrylamide) were used. As shown wit...
متن کاملUse 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.
متن کاملSurface-grafted Hyperbranched Polymers by Self- Condensing Vinyl (co)polymerization via Atrp
Introduction Highly branched polymers play an increasingly important role in interface and surface sciences, since their distinctive chemical and physical properties can be used advantageously as functional surfaces and as interfacial materials. Hyperbranched polymers grafted onto surfaces have also become a field of growing interest. Depending upon the substrates, it can be divided into 3D, 2D...
متن کاملسنتز 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...
متن کاملUse of a simple surface-active initiator in controlled/living free-radical miniemulsion polymerization under AGET and ARGET ATRP conditions.
This communication describes the first example of the efficient use of a simple amphiphilic molecule as both a surfactant and an initiator in the miniemulsion polymerization of methyl methacrylate under AGET and ARGET ATRP conditions.
