摘    要:采用自由基溶液聚合法合成了马来酸酐(MAn)-丙烯酸丁酯(BA)-苯乙烯(St)三元共聚物大分子偶联剂,并用其对纳米氮化铝(AlN)粉体进行了表面改性。通过GPC、FTIR、沉降实验、TGA、接触角以及TEM的分析表明,合成的大分子偶联剂,数均相对分子量在3 000~10 000之间,适于对纳米粉体进行包覆;单体投料摩尔比为1:1:5的MAn-BA-St三元共聚物大分子偶联剂对纳米AlN的改性效果最好,其化学利用率为52.5%,物理利用率为25%;改性后纳米AlN的表面自由能从879 J/M2降至221 J/M2,在苯乙烯中分散良好。

关 键 词:三元共聚物,纳米氮化铝,不饱和聚酯,表面改性

Abstract:A new macromolecular coupling agent,maleic anhydride(MAn)-butyl acrylate(BA)-styrene(St) tercopolymer,was synthesized via solution free radical polymerization and used to modify aluminum nitride(AIN).The molecular structure of the terpolymer was confirmed by FTIR,and its average molecular mass was determined by GPC.The structure,surface properties and thermal stability of the modified nano-AlN were systematically investigated by FTIR,contact angle,TGA,TEM and sedimentation experiment.The results show that t...
Keywords:tercopolymer  nanosized aluminum nitride(AlN)  unsaturated polyester resin  surface modification
