  本发明涉及一种改性淀粉及其制备方法和应用，主要由淀粉和阳离子淀粉络合剂制备得到；所述阳离子淀粉络合剂的化学结构由以下部分构成:i)一个或多个疏水基团，其中至少一个疏水基团能与淀粉反应生成包合络合物，和ii)一个或多个亲水基团，其中至少一个亲水基团为阳离子型亲水基团；所述疏水基团与所述亲水基团分别处于同一分子结构的两端并以化学键相连接，形成一种不对称的、极性的结构。将该改性淀粉用于造纸可以大大提高淀粉在纤维表面或纸浆中的吸附率，从而提高淀粉在纸张中的保留率，从而可以提高纸张强度，并且降低甚至消除淀粉在制浆造纸过程中的流失，从而降低COD排放。

  Polymers with non-leaching antimicrobial activity and their use as surface coatings or bulk resins for medical devices. The antimicrobial polymers are prepared with antimicrobial moieties covalently bonded to a polymer chain end or to a polymer backbone at a side chain end. The antimicrobial moiety-containing endgroups include surface active (or surface assembling) moieties which promote enrichment of antimicrobial endgroups at the polymer surface and thus formation of an antimicrobially active surface. Polymers with built-in antimicrobial endgroups can be used as bulk resins, as antimicrobial additives, or as infection preventative coatings in the manufacture of medical devices (e.g., catheters, vascular access devices, peripheral lines, IV sites, drains, gastric feeding and tubes, and other implantable devices). Such materials can also be used as antimicrobial and antifouling coatings on structures in contact with microorganism in environments that require control of biofilm formation, such as marine products.
