         currently polyurethane ester waste material positive 逐渐堆满 waste 填埋场, 但科学家们 most has can can solutions: development types degradation polyurethane ester methods. 当原始 product to use lifespan, polymer can very easy by solvent understanding manufacturing strong/high force and other new product. this polyurethane ester can used for micro in, this can 打开以释放诸如生 material agent type material.

        “ full world production 数百 10,000 tons polyurethane ester used for foam, plastics, 运动鞋, insulation material and other product, ” in upper show/display this research 博士生Ephraim Morado说, “但 is use rear usually 会丢弃 this material. ” waste polyurethane ester most by 填埋, or 者焚烧. this need a large amount of can amount generate has 毒 副 product. 他指出: “ as is substitute/replace solution/scheme, 我们希望 development lower generation polyurethane ester. it can very easy degradation, again processing formed new material bonding agent or coating material toward market. ”

        当然, Morado并不 is 唯一一 寻求 heavy use polymer methods 科学家. project research 员Steven Zimmerman博士说: “ many for recycling utilizing 感兴趣 人 positive will polymer separation understanding formed raw materials rear heavy new made as same polymer. positive in 采取一 types non different in methods. is it more simple 便宜, short time inner inner has use. ”Zimmerman 实验室位于伊利诺伊 large 学厄巴 nano separation 校. “我们 positive will polymer separation understanding formed industrial upper Common raw materials. ”

        常规 polyurethane ester and Morado polyurethane ester between key/critical difference in 于, Morado polyurethane ester in add 入 羟基 shrink aldehyde as is mono 体之一. Zimmerman 团队首先 use types 特殊 含碘 shrink aldehyde made biodegradable polymer and polypropylene (PP) amine 凝胶. in 团队早期 research in, polymer can solvent understanding in low acid property water in.

        Morado发明 一 types can add non polyurethane ester new type shrink aldehyde. this 样他就 can in has water lower solvent understanding polymer. 经 数 month research, 他发现三 chlorine acid in chlorine 甲烷(一 types has machine solvent agent) in solvent liquid can in short short small inner in room temperature lower solvent understanding polyurethane ester. type method need ultra- 1,400 华氏 degree has gas 体 形 formed, new methods and methods versus ratio for ring requirements large large decrease low. and water different, chlorine 甲烷会 make material 膨胀. this type of make acid can to polyurethane ester separation 子链 主链, make shrink aldehyde chemical fracture. degradation 释放出 alcohol mono 体. this mono rear can used for manufacturing new product. its in bonding agent property can can and ultra- strong/high force versus 媲美.

        Morado also other shrink aldehyde polyurethane ester, 当暴露 in light lower can degradation. use this material manufacturing can remove agent 甚至生 material agent micro 胶囊, used for 杀死藤壶 and other viscous in upper material. and Zimmerman也 positive in development in chlorine solvent agent in use acid 处理时 solvent understanding bonding agent. 另一 潜 in application is in electrical sheet/plate upper: if 原始芯 sheet/slice fault/failure, degradation polyurethane ester can will already solid viscous in electrical sheet/plate upper sheet/slice lower new.

         in addition, 该团队 positive force research polyurethane ester how to in more temperature and conditions (and reaction) decline understanding. this for/regarding biodegradable combined or application (例如 can 拆卸图 sheet/slice device) especially has use.
