很多文獻(xiàn)啊,可以把氯化鈉和你的基材混合,然后再融掉它。 For example :At first, PLA or PLGA sponges were prepared by a particulate- leaching technique using sieved sodium chloride particulates or pre-prepared ice particulates as a porogen. After sodium chloride or pre-prepared ice particulates were removed by washing with water or freeze-drying, porous structures were formed. http://onlinelibrary.wiley.com/d ... 55%3E3.0.CO;2-C/pdf 2F2001&_rdoc=1&_fmt=high&_orig=search&_origin=search&_sort=d&_docanchor=&view=c&_searchStrId=1646345283&_rerunOrigin=scholar.google&_acct=C000050561&_version=1&_urlVersion=0&_userid=4248650&md5=dec6c8e5e4709a045a21062afe8c00f6&searchtype=a#sec2.2 A solution of chitosan (1.5% in weight) in 0.5 aqueous acetic acid was prepared and one of soluble porogens such as sodium chloride, glucose and sucrose was then dissolved in it. The mixture was poured into the mould containing the dry chitosan film at its bottom. The mold was immediately frozen at −28°C and then lyophilized in a freeze-dryer (FTSTM Systems Inc., USA) to give a porous sponge layer over the film.http://www.sciencedirect.com/sci ... _coverDate=02%2F15% |
