由于降解反应生成了亲水性的羟基及羧基，塑料样品的接触角不断降低。PET分子链的降解同样还表现在晶体结构的消融以及分子量的降低上，可以通过X射线衍射以及凝胶渗透色谱法进行验证。同样地，采用以上方法对其他几种塑料的降解过程进行监测及研究，并探究塑料降解过程的机理：塑料的降解过程首先是其在不同溶剂中的溶胀作用，接下来是在无定形区的腐蚀以及结晶区的聚合物链拆解，使得聚合物链打开而增加反应的比表面积，进一步加速反应。在这一过程中，UO22+在460 nm蓝光激发下产生了激发态的*UO22+并活化聚合物的链段。聚合物降解机理可以通过其降解生成的酸或者酚类产物进行分类。对于产生酸类产物聚苯乙烯类及聚酯类塑料样品，其降解过程遵循单电子转移（single electron transfer, SET）和氢原子转移（hydrogen atom transfer, HAT）机理；对于生成酚类单体的聚碳酸酯和聚醚类塑料，其降解机理主要是氧原子转移（oxygen atom transfer, OAT）和单电子转移SET的协同作用他们设计了连续流光反应器，并对公斤级PET实际样品瓶的降解过程进行实验。在降解处理过程中，目标样品瓶不需要前处理或清洗，可在原有标签、色素、黏合剂、发泡剂存在情况下对其进行降解处理。Vim tias cov tshuaj tiv thaiv degradation ua rau hydrophilic hydroxyl thiab carboxyl pawg, lub kaum sab xis ntawm cov qauv yas txuas ntxiv txo qis. Qhov kev ua tsis zoo ntawm PET molecular saw tseem pom nyob rau hauv ablation ntawm cov qauv siv lead ua thiab txo qhov hnyav molecular, uas tuaj yeem txheeb xyuas qhov tseeb los ntawm X-ray diffraction thiab gel permeation chromatography. Ib yam li ntawd, cov txheej txheem saum toj no tau siv los saib xyuas thiab kawm txog cov txheej txheem kev puas tsuaj ntawm lwm hom plastics, thiab tshawb xyuas cov txheej txheem ntawm cov yas ua kom tsis zoo: cov txheej txheem degradation ntawm plastics ua ntej cuam tshuam nws o hauv cov kuab tshuaj sib txawv, tom qab ntawd los ntawm xeb hauv thaj av amorphous thiab polymer saw disassembly hauv thaj av crystalline, uas qhib cov saw polymer thiab nce thaj chaw tshwj xeeb ntawm cov tshuaj tiv thaiv, txuas ntxiv ua kom cov tshuaj tiv thaiv sai. Thaum lub sijhawm ua cov txheej txheem no, UO22generates lub xeev zoo siab ntawm * UO22under xiav lub teeb pom kev zoo ntawm 460 nm thiab ua kom cov ntu polymer. Lub tshuab ntawm polymer degradation tuaj yeem faib raws li cov kua qaub lossis phenolic cov khoom tsim los ntawm nws qhov kev ua tsis zoo. Rau cov qauv polystyrene thiab polyester yas uas tsim cov khoom siv acid, cov txheej txheem degradation ua raws ib qho kev hloov hluav taws xob (SET) thiab hydrogen atom hloov (HAT) cov txheej txheem; Rau polycarbonate thiab polyether plastics uas tsim cov phenolic monomers, qhov kev hloov kho tsis zoo yog feem ntau cov nyhuv synergistic ntawm oxygen atom hloov (OAT) thiab ib qho hluav taws xob hloov SET. Lawv tsim cov tshuab hluav taws xob txuas ntxiv thiab ua cov kev sim rau cov txheej txheem degradation ntawm phaus qib PET cov qauv fwj. Thaum lub sijhawm ua haujlwm tsis zoo, lub hom phiaj ntawm lub raj mis tsis tas yuav tsum tau kho ua ntej lossis ntxuav, thiab tuaj yeem ua rau muaj qhov tsis zoo nyob rau hauv cov ntawv uas twb muaj lawm, xim, nplaum, thiab cov khoom ua npuas ncauj.
