Poly(sodium acrylate) (PSA) can be degraded by consortia of several bacterial species. We investigated the degradation mechanism for PSA (average molecular weight, 2100) by consortium no. L7-98. PSA was used as the sole carbon source in a mineral salt medium. After cultivation, the PSA had...
The study unveiled the internal mechanism through which PHW enhances the ablation performance of ablative materials by reducing thermal conductivity and forming ... K Hui,L Wang,H Qu,... - 《Polymer Degradation & Stability》 被引量: 0发表: 2022年 加载更多来源...
A relationship expressing the dependence of apparent activation energy on the kinetic parameter of the real complex rate equation is derived. The obtained theoretical results are checked for a complex kinetic model of thermal degradation that consists of two simultaneous processes. It is shown that for...
(GC-MS) for the degradation mechanism of guaiacyl-type lignin model polymer composed of β-O-4 linkages.The results showed that the main ways of lignin model polymer degradation were involved with formation and opening of quinone-type structures,cleavage of β-O-4 and Cα-Cβ and oxidation ...
Isothermal decomposition behaviors which take place in the polymer matrix are of paramount importance in the understanding of polymer flame retardancy and processing property. In the present study, the thermal decomposition of polyepoxyphenylsilsesquioxane/epoxy resin (PEPSQ/EP) systems was investigated by...
A review of degradable plastics technology has revealed that several effective copolymer and additive methods are used commercially for photodegradable plastics. However, it was found that all commercial packaging plastics are not biodeg... PP Klemchuk - 《Polymer Degradation & Stability》 ...
The presence of water molecule is an indispensable prerequisite because it causes the hydrolysis of polymer molecules and promotes the survival of the micro-organisms responsible for biological processes (Mohee et al., 2008). The presence of enzymatic degradation differentiates biodegradation from other ...
The degradation laws of shearing performance for reinforced concrete beams were studied by experiment,and the mechanism was studied,too.Based on the above,the predicting models of shearing capacity varying with the corrosion rate of longitudinal reinforcements and stirrups were set up.关键词: corroded...
