intercalation chemistry-
Consequently, with increasing mmt content, the tensile strength and young ' s modulus of hdpe - g - aa / mmt nanocomposites increased, while that of hdpe / mmt composites decreased. moreover, the addition of mmt to hdpe - g - aa decreased the melting temperature and the degree of crystallization of the matrix. these changes may be attributed to high interfacial adhesion between hdpe - g - aa matrix and exfoliated clay, which reduces the mobility of crystallizable pe chain segments, and subsequently reduces the crystallization ability
研究結果表明: mmt在hdpe中不能達到納米級分散,而在hdpe - g - aa中, mmt能以插層型利剝離型的結構存在,這主要是由於極性的丙烯酸接枝在hdpe上提高了後者的極性,而且能與mmt上的活性基團進行化學反應,從而提高了pe鏈進入mmt層間的可能性,使mmt在基體中達到納米級分散。When the content of vermiculite minerals was about 10 %, the impact strength ( nick ) and the flexural strength had maximum value, but those of the polybenzoxazine ( bisphenol a type ) / phlogopite composites had been going down. as the content of vermiculite minerals was over 5 %. hdt of the polybenzoxazine ( bisphenol a type ) / vermiculite hybrid nanocomposites was higher than that of the polybenzoxazine ( bisphenol a type )
