纸和纸板的检验.抗微生物添加剂的检验.甲叉双硫 - It is significant for reducing the product cost and improving the comprehensive property of the superabsorbent composite . using ammonium eerie nitrate and n , n ' - methylene - bis - acrylamide as an initiator and crosslink agent respectively , a superabsorbent composite is prepared by graft polymerization of acrylamide on starch at the presence of clay suspension , followed by hydrolyzing , washing , drying , grounding and filtering
本文以硝酸铈铵为引发剂， n ， n -亚甲基双丙烯酰胺为交联剂，使淀粉、粘土接枝共聚丙烯酰胺，经过水解，洗涤，干燥，粉碎制得粘土-淀粉接枝共聚丙烯酰胺的超吸水性复合材料。 - This dissertation focuses on how to develop a high performance damping mechanism based on multi - energy transitions , which is independent or little dependant with the viscoelasticity of polymer matrix . three sections are mainly included in this dissertation as follows : chlorinated polyethylene ( cpe ) / piezoelectric ceramic ( pzt ) / vapor grown carbon fiber ( vgcf ) composites ; cpe / 2 , 2 ' - methylene - bis - ( 4 - methyl - 6 - cyclohexylphenol ) ( zkf ) / vgcf composites ; organic hybrids made from cpe and small molecules cpe / pzt / vgcf composites : the damping composites of multi - energy transitions mechanism were produced by mixing pzt and vgcf into cpe . in this system , the mechanical vibration energy that was transmitted to cpe was found to convert into joule ' s heat through conduction paths between vgcf in the polymer matrix , so the vibration fades away
本论文主要包括三个方面的研究内容： ?氯化聚乙烯( cpe ) /压电陶瓷( pzt ) /气相生长碳纤维( vgcf )复合材料； ? cpe /双[ ( 2 -羟基- 3 -环己基- 5 -甲基) -苯基]甲烷( zkf ) / vgcf复合材料； ? cpe基有机小分子混杂型复合材料cpe / pzt / vgcf减振复合材料：利用压电和导电填料填充高聚物基体，当复合材料受到机械振动时，通过高聚物基体将机械振动能传递到压电陶瓷粒子上，利用压电陶瓷的压电效应，将机械能转换成电能，则电流在导电粒子产生的回路中流动，由于导电回路具有一定的电阻，所以电能又转变成热能耗散掉，从而起到减振的目的。
